Abstract: We study the LHC search prospects for a model in which the neutrinos obtainDirac masses from couplings to a second Higgs doublet with tiny vacuumexpectation value. The model contains a charged Higgs boson that decays to l nuwith branching fractions controlled by the neutrino masses and mixing angles asmeasured in neutrino oscillation experiments. The most promising signal iselectroweak 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 variableM {T2} eliminates most of the t t and W-pair background. Depending on theneutrino mass spectrum and mixing angles, a 100 300 GeV charged Higgs couldbe discovered at the LHC with as little as 8 24 fb-1 of integrated luminosityat 14 TeV pp center-of-mass energy.
