Baryogenesis via relativistic bubble walls

recommendations! Published in 2021 at "Journal of High Energy Physics"

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.

Baryogenesis from cosmological CP breaking

recommendations! Published in 2025 at "Journal of High Energy Physics"

DOI: 10.1007/jhep11(2025)109

Abstract: We show that baryogenesis can arise from the cosmological evolution of a scalar field that governs CP-violating parameters, such as the Yukawa couplings and the theta terms of the Standard Model. During the big bang,… read more here.

recommendations! Published in 2023 at "Physica Scripta"

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: 10.1103/1tw4-btvy

Abstract: We explore the connection of baryogenesis at temperatures below the electroweak scale and signals for long-lived particles at the LHC. The model features new SM singlets, with a long-lived fermion decaying to quarks to generate… 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.

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.

DOI: 10.1103/physrevd.103.043504

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.
