Multi-Messenger Cosmological Probes for New Physics in the Light of Ya.B. Zeldovich’s Legacy

AbstractThe modern Standard cosmological scenario, reflecting to large extent the development of Zeldovich’s legacy in cosmoparticle physics, involves inflation, baryosynthesis and dark matter/energy. Physics of all these elements of the cosmological paradigm lays Beyond the Standard model (BSM) of elementary particles and involves in its turn cosmological probes for its study. To specify this physics the idea of multi-messenger probes of new physics is proposed, involving the set of additional model dependent consequences of physical models for inflation, baryosynthesis and dark matter. We give a brief review of Cosmophenomenology of new physics, involving multi-component dark matter, metastable particles, Primordial black holes (PBHs) and antimatter domains in baryon asymmetrical Universe.
