Description

In this work, we investigate the possibility of probing a class of three-loop models for neutrino mass at the LHC with 8 and 14 TeV energies. The existence of lepton flavor violating interactions for singlet charged scalar, S±, that couples to the leptons could induce many processes such as pp -> ℓ± ℓ∓ E_{miss}. Using the processes with ℓ ℓ = ee, eμ, μμ, we found that an inclusive cut on the MT2 event variable is vital and leads to an effective suppression of the large SM background. Our results show possible detectability of the charged scalars effect, especially at the LHC@14.
