Electro-Weak Phase Transitions and Collider Signals in the Aligned 2-Higgs Doublet Model
Angela Conaci, Stefania De Curtis, Luigi Delle Rose +4
We show that the Aligned 2-Higgs Doublet Model (A2HDM) is a framework able to simultaneously accommodate strong first order electro-weak phase transitions, in turn generating detec…
Probing the Electroweak Phase Transition in the Dark Sector
Maimoona Razzaq, Nico Benincasa, Luigi Delle Rose +1
We study an extension of the Standard Model with a dark SU(2) gauge group, where a dark scalar doublet interacts with the Standard Model Higgs through a portal coupling, inducing m…
Phase transitions and gravitational waves in a non-abelian vector dark matter scenario
Nico Benincasa, Luigi Delle Rose, Luca Panizzi +2
We study a scenario where the Standard Model is extended by a SU(2) gauge group in the dark sector. The three associated dark gauge bosons are stabilised via a custodial symmetry t…
Electroweak phase transition in a vector dark matter scenario
Nico Benincasa, Luigi Delle Rose, Luca Panizzi +2
This study explores the parameter space of a minimal extension of the Standard Model with a non-abelian group, in which the gauge bosons are stable and acquire mass through…
