15 Feb 2013 | | Abstract: | We study the production and decay of charged scalars, eta^pm, in the context
of a CP-Violating Inert-Doublet Model. The model is an extended version of the
Inert Doublet Model with an extra Higgs doublet and provides new sources of CP
violation and a dark matter candidate. As compared with the 2HDM, the particle
spectrum contains two additional neutral scalars and a charged pair. These
particles are subject to a Z_2 symmetry, but can be pair-produced in hadronic
collisions. If a charged scalar is included in the pair, it decays to the
stable dark-matter candidate (i.e., the lightest neutral inert scalar) plus
Standard Model matter that consists of either two jets or a single lepton (from
a virtual or real W or Z) plus missing transverse energy. Since the single
production channel is available only at hadronic colliders, we consider the
Large Hadron Collider environment, hence we discuss experimental perspectives
and possible hallmarks of the model, such as events with a displaced vertex. | | Source: | arXiv, 1302.3713 | | Services: | Forum | Review | PDF | Favorites | |
