Electroweak symmetry non-restoration and suppressed dark radiation in supersymmetric Twin Higgs model

Journal of High Energy Physics
We investigate a possibility of electroweak symmetry non-restoration (SNR) below the Twin electroweak scale (~ TeV) within the Twin Higgs model. We focus on supersymmetric extensions with light sfermions where SNR is driven by mirror symmetry breaking in

Bridging the μHz gap in the gravitational-wave landscape: unveiling dark baryons

Journal of High Energy Physics
We study gravitational waves (GWs) with frequencies in the μHz range, which arise from phase transitions related to dark confinement in the context of dark versions of Quantum Chromodynamics.

Purely flavored leptogenesis from a sudden mass gain of right-handed neutrinos

Journal of High Energy Physics
In this paper, we would like to point out that in the scenario that the right-handed neutrinos suddenly gain some masses much larger than the temperature of the Universe at that time so that the washout effects for the lepton asymmetry generated from ...

Minimal seesaw and leptogenesis with the smallest modular finite group

Journal of High Energy Physics
We propose a model for leptons based on the smallest modular finite group Γ2 ≅ S 3 that, for the first time, accounts for both the hints of large low-energy CP-violation in the lepton sector and the matter-antimatter asymmetry of the Universe, generated ...

Neutrino reheating predictions with non-thermal leptogenesis

Journal of High Energy Physics
Connecting inflation with neutrino physics through non-thermal leptogenesis via direct inflaton-right-handed neutrino (RHN) coupling naturally incorporates neutrino reheating, leaving no ambiguity regarding the early history of the universe. In ref. [1],

Leptogenesis in five-dimensional asymptotic grand unification models

Journal of High Energy Physics
Asymptotic grand unification models can be constructed in five dimensions compactified on an orbifold. We demonstrate that the parameter space of such models admit solutions that naturally achieve the baryon asymmetry via leptogenesis, these solutions ...

ALP-assisted strong first-order electroweak phase transition and baryogenesis

Journal of High Energy Physics
Axion-like particles (ALPs) can be naturally lighter than the electroweak scale. We consider an ALP that couples to the Standard Model Higgs to achieve the strong first-order electroweak phase transition.
