Abstract: Abstract We present a novel mechanism which leads to the baryon asymmetry generation during the strong first order phase transition. If the bubble wall propagates with ultra-relativistic velocity, it has been shown [1] that it… 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.104.055010
Abstract: Right-handed neutrinos offer an elegant solution to two well established phenomena beyond the Standard Model (SM)—masses and oscillations of neutrinos, as well as the baryon asymmetry of the Universe. It is also a minimalistic solution… read more here.
