Beyond the Standard Model in Particle Physics and Cosmology: Convergence or Divergence?

Abstract

The modern Standard cosmological model of inflationary Unvierse and baryosynthesis deeply involves particle theory beyond the Standard model (BSM). Inevitably, models of BSM physics lead to cosmological scenarios beyond the Standard cosmological paradigm. Scenarios of dark atom cosmology in the context of puzzles of direct and indirect dark matter searches, of clusters of massive primordial black holes as the source of gravitational wave signals and of antimatter globular cluster as the source of cosmic antihelium are discussed.

Hadronic and Hadron-Like Physics of Dark Matter

“…If technilepton number L ′ is conserved, the excess of stable technilepton ζ with charge −2 is possible. In both cases, stable −2 charged particles can capture primordial 4 In all the three cases it was shown that there are parameters of the model at which the techniparticle asymmetries have proper sign and value, explaining the O-helium dark matter density [128,131].…”

“…The nature of dark matter is inevitably linked to beyond the Standard Model (BSM) physics of elementary particles. In the lack of direct experimental evidences for this physics, methods of cosmo-particle physics [1][2][3][4][5][6] are needed for its study involving proper combination of cosmological, astrophysical and experimental physical probes.…”

Cosmological Probes for Supersymmetry

“…Based on [82][83][84][85][86], the antiprotons produced by the fragmentation of gluons emitted by decaying gravitinos were considered as a source of nonequilibrium light nuclei resulting from collisions of those antiprotons on equilibrium nuclei. Then, 6 Li, 7 Li and 7 Be nuclei production by the interactions of the nonequilibrium nuclear flux with 4 He nuclei in equilibrium was taken into account and compared with data (this approach is supported by several recent analyses [87,88] which lead to similar results). The resulting Monte-Carlo estimates [85] lead to the following constraint on the concentration of gravitinos:…”

“…A profound signature of a nonhomogeneous SUSY-based mechanism for baryosynthesis is the appearance of antimatter domains in a baryon asymmetric Universe (Section 7). We conclude that the development of supersymmetric models perfectly illustrates the might of the basic principles of cosmoparticle physics [3][4][5][6][7][8], which studies the physical basis of the modern cosmology and combines probes from cosmology, astrophysics and experimental physics in a systematic way (Section 8).…”

Cosmological Probes of Supersymmetric Field Theory Models at Superhigh Energy Scales

“…Studies of supersymmetric (SUSY) models in field theory and gravity involve proper combination of cosmological, astrophysical and experimental physical probes reflecting methods of cosmoparticle physics [1][2][3][4][5][6] that explores fundamental relationship of cosmology and particle physics. SUSY models provide solutions not only to the hierarchy problem, grand unification and the origin of Higgs mechanism, but also to the mechanisms of inflation, baryosynthesis and nonbaryonic dark matter.…”
