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…
Pseudo-Goldstone dark matter: gravitational waves and direct-detection blind spots
Tommi Alanne, Nico Benincasa, Matti Heikinheimo +4
Pseudo-Goldstone dark matter is a thermal relic with momentum-suppressed direct-detection cross section. We study the most general model of pseudo-Goldstone dark matter arising fro…
