Axion quark nuggets. Dark matter and matter–antimatter asymmetry: Theory, observations and future experiments

We review a testable, the axion quark nugget (AQN) model outside of standard WIMP paradigm. The was originally invented to explain observed similarity between dark and visible components, [Formula: see text], in natural way as both types matter are formed during same QCD transition proportional dimensional fundamental parameter system, text]. In this framework, baryogenesis is actually charge segregation (rather than generation) process which operational due text]-odd field, while global baryon number Universe remains zero. nuggets anti-nuggets strongly interacting but macroscopically large objects with approximately nuclear density. overview several specific recent applications framework. First, we discuss “solar corona mystery” when so-called nanoflares identified AQN annihilation events corona. Secondly, proposal that recently by Telescope Array puzzling result AQNs under thunderstorm. Finally, broadband strategy could lead discovery AQN-induced axions representing heart construction.
