Ligong Bian, Huai-Ke Guo, Yongcheng Wu, Ruiyu Zhou
TL;DR
This paper explores how extra electroweak symmetry breaking contributions influence the vacuum structure, phase transition patterns, and potential signals in collider and gravitational wave experiments, providing new insights into the electroweak symmetry breaking mechanism.
Contribution
It introduces a novel scenario with extra EWSB contributions affecting vacuum structure and phase transitions, and analyzes collider and gravitational wave signals associated with this model.
Findings
Higgs pair searches complement gravitational wave signals in probing the model.
Strongly first-order electroweak phase transition can produce detectable gravitational waves.
Collider limits constrain the parameter space for the phase transition.
Abstract
We study the Electroweak symmetry breaking mechanism with extra Electroweak symmetry breaking contributions (eEWSB) that are bounded by the Fermi constant and limits from the related collider searches. The eEWSB is helpful to build a different zero temperature vacuum structure from the Standard Model (SM), and therefore leads to different Electroweak phase transition patterns at the early Universe. We investigate the collider search prospects and gravitational waves (GW) predictions from the strongly firstly order phase transition (SFOEWPT) in this scenario. The Higgs pair searches at lepton colliders are found to be complementary with the GW searches of the SFOEWPT parameter spaces.
