Abstract: A bstractWe calculate the baryon asymmetry of the Universe in the ℤ3$$ {\mathbb{Z}}_3 $$-invariant Next-to-Minimal Supersymmetric Standard Model where the interactions of the singlino provide the necessary source of charge and parity violation. Using the… read more here.

DOI: 10.1016/j.nuclphysb.2019.114643
Abstract: Abstract I suggest a new extension of the standard model of particle physics, which introduces a dark sector with the S U ( 2 ) D ⊗ U ( 1 ) D ′ symmetry besides… read more here.

DOI: 10.1088/1475-7516/2021/07/049
Abstract: We show that the baryon asymmetry of the universe can be explained in models where the Higgs couples to the Chern-Simons term of the hypercharge group and is away from the late-time minimum of its… read more here.

DOI: 10.1103/physrevd.104.083524
Abstract: We have refined our previously suggested scenario of generation of the cosmological baryon asymmetry through an asymmetric capture of baryons and antibaryons by primordial block hole [30]. It is found that in the limit of… read more here.
