Multi-messenger cosmology of new physics
Maxim Yu. Khlopov
TL;DR
This paper discusses how various cosmological observations serve as messengers revealing new physics beyond the Standard Model, including dark matter, primordial black holes, and antimatter domains, shaping our understanding of the Universe's origin and evolution.
Contribution
It introduces multiple model-dependent messengers such as multi-component dark matter and primordial black holes to specify physics beyond the Standard Model in cosmology.
Findings
Cosmological evidence supports inflation, baryosynthesis, and dark matter/energy as messengers of new physics.
Proposes additional messengers like meta-stable particles and antimatter domains.
Highlights the role of these messengers in understanding the Universe's origin and structure.
Abstract
The observational evidence for the inflationary cosmology with baryosynthesis and dark matter/energy can be viewed as the messenger for new physics, which governed the Universe origin, evolution and structure. To specify the physics beyond the Standard model (BSM), underlying the modern cosmological paradigm additional model dependent messengers are proposed, involving multi-component and composite dark matter, meta-stable particles, primordial black holes and antimatter domains in baryon asymmetrical Universe.
