Strong Electroweak Phase Transition in a Model with Extended Scalar Sector
We consider an extension of the Standard Model (SM) with additional gauge singlets which exhibits a strong first‐order phase transition. Due to this first‐order phase transition in the early universe gravitational waves are produced. We estimate the contributions such as the sound wave, the bubble wall collision, and the plasma turbulence to the ...

Electroweak baryogenesis driven by extra top Yukawa couplings
We study electroweak baryogenesis driven by the top quark in a general two Higgs doublet model with flavor-changing Yukawa couplings, keeping the Higgs potential CP invariant.

Spontaneous baryogenesis from asymmetric inflaton
We propose a variant scenario of spontaneous baryogenesis from asymmetric inflaton based on current–current interactions between the inflaton and matter fields with a non-zero B−L charge.

Electroweak baryogenesis (EWBG) remains a theoretically attractive and experimentally testable scenario for explaining the cosmic baryon asymmetry. We review recent progress in computations of the baryon asymmetry within this framework and discuss their ...

Affleck–Dine baryogenesis via mass splitting
We introduce a class of non-supersymmetric models explaining baryogenesis a la Affleck–Dine, which use a decay of two superheavy scalar fields with close masses.

Among various scenarios of baryon asymmetry of the Universe, electroweak baryogenesis is directly connected with physics of the Higgs sector. We discuss spectra of gravitational waves which are originated by the strongly first order phase transition at ...

The impact of particle production on gravitational baryogenesis
Baryogenesis driven by curvature effects is investigated by taking into account gravitationally induced particle production in the very early Universe. In our scenario, the baryon asymmetry is generated dynamically during an inflationary epoch powered by

Moduli-induced baryogenesis [PDF]
We study a scenario for baryogenesis in modular cosmology and discuss its implications for the moduli stabilization mechanism and the supersymmetry (SUSY) breaking scale. If moduli fields dominate the Universe and decay into the standard model particles through diatonic couplings, the right amount of baryon asymmetry can be generated through CP ...
