Baryogenesis via relativistic bubble walls

DOI: 10.1007/jhep10(2021)043
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: 10.1088/1402-4896/accbf2
Abstract: Entropy is defined as a measure of the degree of disorder or randomness in a system and is expressed in thermodynamic terms as the inability of thermal energy to be converted into mechanical work. In… read more here.

DOI: 10.1088/1475-7516/2021/01/022
Abstract: Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global U(1) symmetry that can play the role of baryon or lepton… read more here.

DOI: 10.1098/rsta.2017.0124
Abstract: The origin of the matter–antimatter asymmetry of the universe remains unexplained in the Standard Model (SM) of particle physics. The origin of the flavour structure is another major puzzle of the theory. In this article,… read more here.

DOI: 10.1103/physrevd.100.015034
Abstract: We show that spontaneous baryogenesis occurs automatically in relaxion models if the reheating temperature is larger than the weak scale, provided the Standard Model fields are charged under the U(1) of which the relaxion is… read more here.

DOI: 10.1103/physrevd.100.103525
Abstract: We explore the possibility of baryogenesis in the framework of quintessential inflation. We focus on the model independent features of the underlying paradigm and demonstrate that the required baryon asymmetry can successfully be generated in… read more here.

Adiabatic electroweak baryogenesis driven by an axionlike particle

DOI: 10.1103/physrevd.101.035009
Abstract: An axion-like particle (ALP) offers a new direction in electroweak baryogenesis because the periodic nature enables it to trigger a strong first-order phase transition insensitively to the decay constant $f$. For $f$ much above TeV,… read more here.

Abstract: In models of baryogenesis based on grand unified theories (GUTs), the baryon asymmetry of the Universe is generated through the $CP$ and baryon number violating, out-of-equilibrium decays of very massive gauge or Higgs bosons in… read more here.

DOI: 10.1103/physrevd.105.015024
Abstract: We consider a chiral gauge theory from which light composite Dirac neutrinos dynamically emerge, augmented by a QCD axion to solve the strong CP problem. We show that an interplay between the composite sector and… read more here.

Abstract: We consider a baryogenesis scenario via the oscillation of right-handed neutrinos with Majorana masses of the order of GeV, which are also responsible for neutrino masses by the seesaw mechanism. We study how the initial… read more here.

DOI: 10.1103/physrevd.97.075008
Abstract: The link between a modified Higgs self-coupling and the strong first-order phase transition necessary for baryogenesis is well explored for polynomial extensions of the Higgs potential. We broaden this argument beyond leading polynomial expansions of… read more here.
