Amine Ahriche (Jijel U.)
TL;DR
This paper investigates the strength of the electroweak phase transition within the UMSSM, showing it can be strongly first order without exotic fields, depending on Higgs and neutralino masses.
Contribution
It demonstrates that the UMSSM can exhibit a strongly first order electroweak phase transition without exotic fields, expanding understanding of phase transition dynamics in supersymmetric models.
Findings
EWPT can be strongly first order in UMSSM
No exotic fields needed for strong EWPT
Depends on lightest Higgs and neutralino masses
Abstract
In this work, the electroweak phase transition (EWPT) strength has been investigated within the extended Minimal Supersymmetric Standard Model (UMSSM) without introducing any exotic fields. We found that the EWPT could be strongly first order for reasonable values of the lightest Higgs and neutralino masses.
