24 May 2017 | | Abstract: | Vector-like fermions charged under both the Standard Model and a new dark
gauge group arise in many theories of new physics. If these fermions include an
electroweak doublet and singlet with equal dark charges, they can potentially
connect to the Higgs field through a Yukawa coupling in analogy to the standard
neutrino portal. With such a coupling, fermion loops generate exotic decays of
the Higgs boson to one or more dark vector bosons. In this work we study a
minimal realization of this scenario with an Abelian dark group. We investigate
the potential new Higgs decays modes, we compute their rates, and we study the
prospects for observing them at the Large Hadron Collider and beyond given the
other experimental constraints on the theory. We also discuss extensions of the
theory to non-Abelian dark groups. | | Source: | arXiv, 1705.8896 | | Services: | Forum | Review | PDF | Favorites | |
