Patras 2022 - 46 - Igor Samsonov - Quark Nugget Dark Matter: hunter’s guide

Igor Samsonov from the University of New South Wales, Australia, talks about "Quark Nugget Dark Matter: hunter’s guide" at the 17th Patras Workshop on Axions, WIMPs and WISPs.
The Patras Workshop took place at the Johannes Gutenberg University of Mainz as the second week of events within the Wavy Dark Matter Summer event series in August 2022. www.wavydarkmatter.org
Abstract:
Dark matter particles may be represented by compact composite objects
of quark matter with macroscopic parameters of mass, charge
and effective temperature. Such particles remain cosmologically and
observationally dark if they possess a small cross section to mass
ratio. A new feature of the Quark Nugget dark matter model is the
prediction of existence of anti-quark nuggets (anti-QNs) built of antimatter
and, thus, strongly interacting with visible matter. We study
various types of radiation which such anti-QNs can produce, including
thermal radiation and gamma photons from matter-antimatter
annihilation. Assuming that these particles constitute the dominant
dark matter fraction in our galaxy, we then estimate their radiation
in our galaxy and compare it with various satellite and terrestrial
observations. New detection approaches of this type of dark matter
are proposed.
