  In this work, we probe a class of neutrino mass models through the lepton
flavor violating interactions of a singlet charged scalar, $S^{\pm}$ 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
$pp\rightarrow\ell^{\pm}\ell^{\pm}\ell^{\mp}+\slashed{E}_{T}$. 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 $\sqrt{s}$= 8 TeV and
$\sqrt{s}$ = 14 TeV.
