In this work, we probe a class of neutrino mass models through the lepton flavor violating interactions of a singlet charged scalar, class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0370269316305263&_mathId=si1.gif&_user=111111111&_pii=S0370269316305263&_rdoc=1&_issn=03702693&md5=c2c9905f97ed0366968822180dded367" title="Click to view the MathML source">S^±class="mathContainer hidden">class="mathCode"> at the LHC proton–proton collisions with 8 TeV and 14 TeV energies.
