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 closed time path formalism, we derive and solve transport equations for the cases where the singlet acquires a vacuum expectation value (VEV) before and during the electroweak phase transition. We perform a detailed scan to show how the baryon… Expand

Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories
The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatter asymmetry of theExpand

The higgsino–singlino sector of the NMSSM: combined constraints from dark matter and the LHC
A light singlino is a promising candidate for dark matter, and a light higgsino is natural in the parameter space of the NMSSM. We study the combined constraints on this scenario resulting from theExpand
Strong first-order phase transitions in the NMSSM --- a comprehensive survey
Motivated by the fact that the Next-to-Minimal Supersymmetric Standard Model is one of the most plausible models that can accommodate electroweak baryogenesis, we analyze its phase structure byExpand
Review of cosmic phase transitions: their significance and experimental signatures.
TLDR
Different types of phase transitions that can appear in cosmic history, and their applications and experimental signatures in particular in the context of exciting gravitational waves, are reviewed, which could be potentially be constrained by LIGO/VIRGO, Kagra, LISA, and Decigo. Expand

GUT baryogenesis with primordial black holes
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 veryExpand
Electroweak baryogenesis and electron EDM in the B-LSSM
Electroweak baryogenesis (EWB) and electric dipole moment (EDM) have close relation with the new physics beyond the standard model (SM), because the SM CP-violating (CPV) interactions are notExpand
Electroweak baryogenesis at high bubble wall velocities
It is widely believed that electroweak baryogenesis should be suppressed in strong phase transitions with fast-moving bubble walls, but this effect has never been quantitatively studied. We rederiveExpand

Nonlocal electroweak baryogenesis. I. Thin wall regime.
TLDR
This paper gives an analytic treatment of quantum mechanical reflection in the thin wall regime, in which interactions with the plasma can be neglected as a particle propagates across the wall, and calculates the baryon asymmetry for various parameter ranges and concludes that asymmetries comparable with observations can be generated.
