“…Cosmological messengers of new physics can help to remove conspiracy of BSM physics, related with absence of its experimental evidence at the LHC, as well as conspiracy of BSM cosmology, reflected in concordance of the data of precision cosmology with now standard ΛCDM cosmological scenario [12]. Multimessenger cosmological probes can provide effective tool to study new physics at very high energy scale [13,14]. Signatures for new physics play especially important role in these studies.…”

Now Standard ΛCDM cosmology is based on physics Beyond the Standard Model (BSM), which in turn needs cosmological probes for its study. This vicious circle of problems can be resolved by methods of cosmoparticle physics, in which cosmological messengers of new physics provide sensitive model dependent probes for BSM physics. Such messengers, which are inevitably present in any BSM basis for now Standard cosmology, lead to deviations from the Standard cosmological paradigm. We give brief review of some possible cosmological features and messengers of BSM physics, which include balancing of baryon asymmetry and dark matter by sphaleron transitions, hadronic dark matter and exotic cosmic ray components, a solution for puzzles of direct dark matter searches in dark atom model, antimatter in baryon asymmetrical Universe as sensitive probe for models of inflation and baryosynthesis and its possible probe in AMS02 experiment, PBH and GW messengers of BSM models and phase transitions in early Universe. These aspects are discussed in the general framework of methods of cosmoparticle physics.
