Description

In this talk I want to discuss the (unorthodox) scenario when the baryogenesis is replaced by a charge separation process in which the global baryon number of the Universe remains zero. In this, the so-called axion quark nugget (AQN) dark matter model the unobserved antibaryons come to comprise the dark matter in the form of nuclear density nuggets. I specifically focus on several recent papers written with Particle Physics, Nuclear Physics and Astro-physics people to apply these generic ideas to several recent proposals. In particular, I will discuss the broadband search strategy of relativistic axions which always accompany the AQN interaction with surrounding material. I will also discuss how the excess of the observed UV radiation in our galaxy can be understood within the same framework.
I will also mention how a number of mysterious and puzzling observations recorded on Earth could be also originated from the same new paradigm when the DM is in fact represented by strongly interacting objects. .
