10. Vector SIMP dark matter with approximate custodial symmetry

Mathias Pierre (IFT UAM-CSIC)

Strongly Interacting Massive Particles (SIMPs) have recently been proposed as light thermal dark matter relics. Here we consider an explicit realization of the SIMP mechanism in the form of vector SIMPs arising from an SU(2)X hidden gauge theory where the approximate custodial symmetry determines comparable but split masses for SU(2)X gauge bosons We will discuss the various several ways of...

26. Electrowek phase transition in a model for dark matter and muon g-2 anomaly

Phenomenological consequences of the strong first-order electroweak phase transition are discussed in an extension of the standard model with an inert doublet and vector-like leptons motivated by dark matter and the muon g−2 anomaly. We point out that a condition for the strong first-order electroweak phase transition inevitably induces a large logarithmic enhancement in Z boson decays, which...
