- New results from the CMS and ATLAS collaborations prove couplings between the Higgs boson and the heaviest elementary particle known, the top quark.
Interviews with ATLAS and CMS physicists on new results that show that the top quark acquires its mass from the Higgs field.
According to the Standard Model, the more a particle interacts with the Higgs boson - or more precisely with the invisible quantum field from which the boson arises - the heavier the particle is. The top quark, being the heaviest elementary particle known, should therefore have the largest interaction strength with the Higgs field. This interaction strength can be directly probed by looking at how often a Higgs boson is produced together with a pair of top quarks. But this process, known as ttH production, isn't easy to measure. For one, it's rare: its likelihood, or cross section, is only 1% of the total cross section for producing the Higgs. For another, the Higgs and the top quarks decay into other particles in many complex ways, or modes.
The latest studies from the CMS and ATLAS teams were presented in Bologna at the sixth annual Large Hadron Collider Physics conference,. Using data from proton-proton collisions collected at an energy of 7, 8, and 13 TeV, the CMS team performed several independent searches for ttH production, each targeting a different Higgs-decay mode (W bosons, Z bosons, photons, τ leptons, and bottom quark jets). To maximise the sensitivity to the sought-after ttH signal, the researchers then combined the results from all of the searches, finding an excess of decay events over the "no-ttH-production" hypothesis with a statistical significance of more than five standard deviations (five sigma) - the gold standard of proof for a discovery in particle physics. What's more, the result is consistent with the Standard Model prediction for ttH production.
The ATLAS researchers did a similar analysis, targeting some of the Higgs-decay channels probed by CMS and other and combining them to boost the sensitivity to the ttH signal. They too found an excess of events.
In addition to representing the first observations of a new way in which the Higgs boson can be produced (with a pair of top quarks), the new findings by CMS and ATLAS show that the Higgs boson interacts with the top quark with a strength that is consistent with that predicted by the Standard Model.

Nice work guys. Look forward to hearing more.
It's happy to see how there are people from several countries. It shows how science it's acually a global thing.
Two out of three are Italians and I am always surprised that such brilliant minds are not able to grasp a decent English accent. I do not say good .. I mean decent. I am Italian and I know that most of my fellow citizens do not even suspect that English features sounds that we do not have in Italian . I am stressing this point because I feel so much superior to them in this matter :-)
Francesco Martella
They are still more brilliant then you Troll
Daniel Garcia it's actually a European thing, not a global thing, cern is in Europe the old continent
Carlos Barros Yeah, we know it's on Europe. What I mean with "science it's a global thing" it's that you can see people from almost everywhere working for humanity progress.
Chris, you sound like another idiot
As always, fascinating. One wonders what remarkable developments may stem from this research. Bravo, CERN!
Great Job. Cheers for uploading
THAT’S a relief! For a minute there I was worried about the top quark.

Jonny Nik ha
Hmmm, Yes I see.. Yes quarks..
+Resonance of Illumination - Ambition of Void Yes, and 0 morphes into 1 by Definition.............
- Theres is an energy field everywhere in the universe, including in your body, called Higgs Field.
- This field has a particle called Higgs Boson.
- Its the Higgs Boson who will give mass to particles.
- Without the Higgs Boson matter would not exist. Everything would be energy.
- Majority of our mass is made by quarks, because 3 quarks put together form a proton or a neutron that are the center of the atoms. So its an important discover.
Qué buen video. Además el comprobar experimentalmente las predicciones matemáticas es fascinante.
Amazing!!
Congratulations!
Amazing
Top quark says to bottom quark. "Does this Higgs make my hips look big?"
Richard Hogan I understand your humour but this is not the place to say such things......
soo don't comment such things
indeed see the hardship of prof. Higgs
Stacker, this _is_ the place to make a Higgs joke.
It would make no sense whatsoever doing it on a baseball, Justin Bieber or cute kitten video...
Says the Gluon
Richard Hogan
"Yes, but only when I'm looking"
I'm so sorry Stacker. I failed to realize that the inquisition is still at large and free thought is still suppressed. Sooo, I sincerely do hope your life gets better and hope you look at the stars before trying to speak to someone else excercising their freedom of speech. By the way, I will check out the hardship of prof. Higgs. We all ride on the backs of the great ones.
This better mean hoverboards for next christmas.
wow . cern is opening the gate for theory of everything
I can just sense all my many quarks stressing against the Higgs Field...giving me just enough mass to get through the day. Veritaseum (sp?) first turned me on to this notion. Good to see more data coming in to reinforce a valid hypothesis. Cheers!
amazing discovery
amazing
Awesome finding! What is the d.o.i for the official paper released?
Kenji Sato Macfarlane arxiv.org/abs/1806.00425
What I know about the atom,is when you rip the atom,the matter is simplified enough to get annihilated by antimatter, hidden in the atom.The need for annihilation must be one of the force in phisics.
I understand that this is very significant and a major step towards a theory of everything. Well done CERN.

yet flat earthers still exist & vote
And reproduce
I agree, but so do atheists
Guts
Gee you have to be a flat earther
Hahaha not at all, but I'm also not a chaotic nihilist
Guts are you brainwashed too? Sad
And a quark for Master Mark! It's not as if one might confuse it with Quark/kvark...
I knew it !
Goodie, oneday.
So it's the higs field that bends spacetime, or is it the other way?
How does the igs field is bound to the electromagnetic field and what those 2 fields are made of, some particle we have not found yet?
And the anti-higs field (dark energy) is it made of anti-higs particles, is there any way such do exist?
1. You are confusing the Higgs field with the gravitational field.
2. dark energy wouldn't be "anti-gravity" (which doesn't exist anyway) as gravity is about space-time curvature and dark energy about accelerated space-time expansion.
3. Particles are excitations of a quantum field. So particles are made of fields rather than the other way around. A quantum field is the (currently) most fundamental description of reality. It's not made of anything other than information & energy in space and time.
3. The Higgs field doesn't couple with the electromagnetic field. That's why photons are massless.
4. An anti-Higgs or anti-Graviton doesn't exist. Only Fermions (matter particles) have anti particles...Bosons (force particles) don't.
I'm a bit confused now, is there a gravitational field or is there a curved space-time?
Once space expand faster than the speed of light the curvature cannot propagate anymore, look at it how you want, space expansion or negative acceleration, it still is "anti-gravity".
The only question is will space expand forever
Photons don't have rest mass, but that's just because they are never at rest, they do have energy and that is the same as having mass, and do behave like any other mass does.
In QFT gravity is conceptualized as a gravitational quantum field with the corresponding particle the Graviton. In GR gravity is abstracted as a space-time curvature. That's why the two are not working together and hence require a yet more fundamental theory of physics. (For which there are several candidates)
No photons are massless (but they have momentum) . That's why they propagate at the speed of light...
Space doesn't expand faster than c. It doesn't expand with any velocity...that's a common misconception. The velocity is a relative attribute of two given points receding from each other. (not through space but with expanding space between them). This "velocity" is only beyond the speed of light if enough space is between the two points.
Nevertheless this has nothing to do with the hypothised "anti-gravity". Gravity pulls objects >through< space together. "Anti-gravity" would push objects >through< space apart based upon their mass. It also would curve space-time but create "mountains" instead of "valleys".
But it doesn't exist anyway...
Just a geek, no education, but does that make quarks, electrons and neutrons? I feel like I'm missing one too.
Edit: not missing anything, I thought this was a new particle and not new proof, as opposed to the inferred proof we had before
Ohh, great
Hi I have questions about string theory and M-theory
.This theory-M is for the consolidation of five versions To those superstrings
.There are tendons and there are membranes in the theory-M
.The tendons have spatial dimensions These dimensions are wrinkled in different forms In the theory of super tendons
.But the question about the membranes in the theory -M Are there wrinkled dimensions in the membranes? .Are there different forms of those membranes in M-theory .Are those membranes vibrating and moving like super strings? .Super tendons differ from membranes in M-theory
.First question: Does the membrane vibrate and give particles of energy
.The second question is whether the membrane also contains twisted dimensions such as tendons?
.Question III Do membranes have different geometric shapes?
. Question 4: What is the reason for the different geometric shapes of these membranes? . Please send these four questions to cosmologists
I sense a Higgs diet coming soon. ;)
Antimatter fields too
We were correct, thats
disappointing
29.07. you know what you want to know, pull the plug now! It's becoming dangerous!
shouldn't this say "demonstrating" not "proving"?
there's no such thing as irrefutable proof in physics, only observation and strong enough statistical significance of it. math is for proofs.
yes.. that's my point.
Your point is idiotic... It's playing semantics for no good reason..
I disagree
can someone please make a gif/meme out of 2:05, to reference mediclorians?!
wouldnt that mean that our own physical body its from another dimension?
mihai md
It means that your physical body is a symphony of waveforms in several oscillating systems.
Whether that requires more than 3D+time, is still a matter of conjecture.
How close are you in creating an energy cell that can recycle on its own energy?
As close as thermodynamics allows.
Mass is created by the transfer of energy to the Higgs field then back to the charged particle. We cannot have mass without the Higgs field and this interaction with charged particles.
What does the Higgs field apply to the energy in order to create the mass. Is it magnetism? Micro to the Macro?
Energy and mass are different words for the same thing, or manifestation of the same thing. The Higgs field converts energy in to all you see around you, and probably the multiverse, that we do not see, but know it must be there.
Yes but what does the Higgs Field do to the energy to convert it? Apply resonance? Magnetic field? I can't help but think plasma is involved in the field. Like in the ISS dusty plasma crystal experiments.
How small is it (05) The Higgs Boson David Butler is worth watching. Quantum physics suggests that mass is from the oscillations of particles travelling through the Higgs field. It is the particle/wave thing. The observation of the top quark interacting with the Higgs field, to me, suggests this to be true.
TJ Green, thank you for that. I did watch it. Matter Fields. The energy disturbs the matter fields resulting in confined matter, which is what we see as matter in our reality. Though he does a good job of explaining how the different particles interact and phase shift to form matter, he doesn't explain where the higgs matter field comes from in the first place. So since you say matter = energy, is the Higgs field more like an ocean of diffused charge, which get's disturbed by energy flowing through it, creating confined field charges, which creates the fermions and bosons, to form the lattice structure of matter?
No "proof" but "strong statistical evidence"!
Yup, so strong that it's considered proof in the physics community.
I don't think any experiment on this level will ever be able to reach 100% but the current number of 5.8 sigma (something like 99.99999%) is pretty close.
3 or 4 sigma would be "strong statistical evidence"
d5uncr the word "proof" is obviously reserved to mathematics but not to experimental physics...
Well, let's call it a "proof beyond reasonable doubt"...
d5uncr I agree for this consensus....
Any experiment of any kind, in the real world, will give data with some kind or margin of error. This margin of error will always prevent a result of 100%.
Negative matter, negative matter everywhere
And nowhere at the same time in the happy fun place of quantum physics haha XD
Soooo.... in a way they are saying the Aether is back :D
A little? The Higgs field is a scalar quantum field; it doesn't have a sense of 'direction' to it, per se, so it's not like you could use it as an 'objective' reference frame in the way the classic Aether was meant to be. Quantum fields, in general, can't really be used as reference frames in that way - I'm by far no expert, so the exact explanation as to why is rather fuzzy, but yeah.
Higgs Field coupling, to my limited understanding, is responsible for the (inertial) masses of elementary particles; larger systems, like atoms, molecules, doorknobs, etc, get most of their mass from the energy of the binding forces between particles - the actual particle masses due to Higgs mechanism is a very small part of a macroscopic object's total mass. Fun stuff.
Quantum field theory has a very small similarity with the ether theory. The fields are everywhere as the ether was thought to be. That's it.
No No there is elaborate FIBBING going on here.
Paul Wittekind please provide your extensive research and years of work, summarized in a research paper that clearly shows that cern is lying.
Hi guys happy to hear about this progress in elementary particle physics but if a bald android called Nardol and a human being called Bill suddenly appear in that nice rest area i can see in the background you may have to rethink your ideas.... (Joke, that some of you may get).
Very interesting, but I wouldn't call a proton hydrogen, because it lacks the electron, while it normally only occurs as H2 too. Like they are testing me.
Joey Grotentraast
It's a hydrogen ion.
Ions..
Did somebody call a proton hydrogen? He said "Which means you can have hydrogen"?
Paul Bartley
Yes, as the proton will inevitably pick up an electron to become hydrogen.
It is good to see some progress. But still we have mass in almost everything with only 1% of the interactions in a rare event. That can't be the answer or there is a big missing piece.
1969nitsuga can you say that in 'proper English' again?!
1969, the Higgs field and the Top quarks interact all the time, it's just the particular (some pun intended) "ttH production" - where a pair of top quarks emit a Higgs boson - that's rare.
d5uncr Exactly, they are assigning mass to that process. Mass is a permanent parameter not emergent. Otherwose it would by theoricaly possible to have a macro object without mass.
Well, the Higgs _field_ assigns mass to the quarks. And it obviously does so all the time.
It's just that the particular Top/Antitop quark and Higgs *boson* pairing they've been able to detect is a rare instance.
Remember that the Higgs *boson* is just a momentary fluctuation in the permanent Higgs _field_ ...
d5uncr The Higgs field is a scalar field in transversed waves, maybe just an extension of the ether. But quarks are bound by couplings and entanglements making the process more generalized and permanent. As you said it is a rare event but it is part of a bigger picture.
Trump field does not couple with CERN. Yay..!
for some reason the accents really started to annoy me so stopped watching

Hello, we will talk about superstring theory ،I have six points in order to discover the super tendons ،The first point is to prepare a very giant screen ،This giant screen is connected with wires to a lens photographing the contents of the quarks Which are contained within neutrons, protons and electrons ،The second point is that the screen must be very giant sophisticated and powerful ،The third point must be a strong and sophisticated microscope lens ،The fourth point is there must be buttons To control zoom in and zoom out the contents of the quarks inside the corn particles ،The fifth point should be the buttons associated with the giant screen controller ،The sixth point is to communicate with the e-companies of the Tablet PC's developer In order to detect super-strings within the quarks
.
your theories do not seem to make sense at all
Paul Wittekind just because they don't make sense to someone who doesn't understand physics, doesn't mean they don't make sense.
Yap, so thats were all the billions of euros went.
ignorance at its best.
You really sound like an idiot. Have you ever considered that actually without people like Galileo, Newton, Einstein, Bohr, Feynman our civilization would not basically exist? Has your brain ever touched such thing? You who probably drive a car, watch TV, call people on the phone, take advantage of lasers, etc etc etc etc etc etc etc etc . These comments really touch my nerves because I am terrorized of the fact that people like you may take full control of the world one day... and no science is not democratic, is the least democratic thing ever
Yeah i think it is better than funding wars and weapon industry
People forget that scientists don't walk up to some scientific discovery supermarket and hand over billions of euros in exchange for a discovery.
The particle accelerators are built, employing thousands of engineers and construction workers for years. The researchers do stuff like buy housing and groceries, which goes into the local economy. Technology advances because of basic science - nobody just suddenly thought up antibiotics or atomic bombs, they were the result of decades or centuries of humdrum discoveries.
It's stupid to say that billions were spent on this. Billions were spent on salaries, capital investments, support of local businesses, etc., and as an added bonus, science advanced.
Wow, so little.
Their whole theory is flawed but still they manage to get the right wrong results.
Please clarify and factually support your statement.
Frédéric Chopin He stayed in a holiday inn express last night so clearly he is entitled to cast doubt and poo poo Nobel prize winning physicists life's work in quantum field theory and Higgs boson postulation and discovery.
PS sorry if you do not live in the US and understand the "Holliday inn express" reference
Maybe he's a proponent of String Theory &/or Super-Symmetry :P
Or just a troll idk lol
Then why don't you prove modern physics wrong and get a Nobel Prize ?
