Cosmological phase transition, baryon asymmetry, and dark matter Q-balls [PDF]
, 2013 We consider a mechanism of dark matter production in the course of first order phase transition. We assume that there is an asymmetry between X- and anti-X-particles of dark sector. In particular, it may be related to the baryon asymmetry. We also assume

Baryon asymmetry and neutron EDM
, 1998 Baryon asymmetry of the universe can be generated by new sources of $CP$ violation intrinsic in supersymmetric extension of the standard model. This scenario predicts the neutron electric dipole moment to be not much smaller than its present experimental upper bound.

Generating the observed baryon asymmetry from the inflaton field [PDF]
, 2013 We propose a mechanism by which the inflaton can generate baryogenesis, by taking the inflaton to be a complex scalar field with a weakly broken global symmetry, and present a new version of the Affleck--Dine mechanism.

Origin of cosmological baryon asymmetry
Physics Letters B, 1979 Abstract A new version of cosmological baryon generation is examined. In this scheme the baryon asymmetry is caused by the nonequilibrium decay of an X(leptoquark) and X† boson of ∼1016 GeV, which takes place after an equilibrium period of baryon nonconserving two-body reactions.

Baryon asymmetry generation in the E 6 CHM
Physics Letters B, 2017 In the E6 inspired composite Higgs model (E6CHM) the strongly interacting sector possesses an SU(6) global symmetry which is expected to be broken down to its SU(5) subgroup at the scale f > 10 TeV. This breakdown results in a set of pseudo-Nambu-Goldstone bosons (pNGBs) that includes one Standard Model (SM) singlet scalar, a SM-like Higgs doublet ...

CP asymmetries in Strange Baryon Decays
Chinese Physics C, 2018 While indirect & direct CP violations (CPV) had been established in the decays of strange & beauty mesons, none have been done for baryons. There are different "roads" for finding CP asymmetries in the decays of strange baryons; they are highly non-trivial ones.

Superheavy monopoles and baryon asymmetry
Physics Letters B, 1982 Abstract It is argued that 't Hooft-Polykov monopoles are highly composite and contain effectively 1/α gauge and Higgs quanta. Thus mm annihilation will yield on the average n H ≈ n rmW ≈ 1/α . In particular superheavy monopoles can annihilation into the SU(5) Higgs leptoquarks.
