A Real Triplet-Singlet Extended Standard Model: Dark Matter and Collider Phenomenology
Nicole F. Bell, Matthew J. Dolan, Leon S. Friedrich +2
We examine the collider and dark matter phenomenology of the Standard Model extended by a hypercharge-zero SU(2) triplet scalar and gauge singlet scalar. In particular, we study th…

Two-Step Electroweak Symmetry-Breaking: Theory Meets Experiment
Nicole F. Bell, Matthew J. Dolan, Leon S. Friedrich +2
We study the phenomenology of a hypercharge-zero SU(2) triplet scalar whose existence is motivated by two-step electroweak symmetry-breaking. We consider both the possibility that…

Electroweak Baryogenesis with Vector-like Leptons and Scalar Singlets
Nicole F. Bell, Matthew J. Dolan, Leon S. Friedrich +2
We investigate the viability of electroweak baryogenesis in a model with a first order electroweak phase transition induced by the addition of two gauge singlet scalars. A vector-l…
