LHC phenomenology of a two-Higgs-doublet neutrino mass model

Understand

We study the LHC search prospects for a model in which the neutrinos obtain Dirac masses from couplings to a second Higgs doublet with tiny vacuum expectation value.

• The model contains a charged Higgs boson that decays to l nu with branching fractions controlled by the neutrino masses and mixing angles as measured in neutrino oscillation experiments.
• The most promising signal is electroweak production of H+ H- pairs with decays to l l' pTmiss, where l l' = e+ e-, mu+ mu-, and e+- mu-+.
• We find that a cut on the kinematic variable M_{T2} eliminates most of the t t and W-pair background.
