Probing radiative neutrino mass models using trilepton channel at the LHC

In this work, we probe a class of neutrino mass models through the lepton flavor violating interactions of a singlet charged scalar, S± at the LHC proton-proton collisions with 8 TeV and 14 TeV energies. This scalar couples to the leptons and induces many processes such as pp→ℓ±ℓ±ℓ∓+E̸T. In our analysis we discuss the opposite sign same flavor leptons signal, as well as the background free channel with the tau contribution which can enhance the signal/background ratio for center of mass energies s=8 TeV and s=14 TeV.
