TL;DR

This paper investigates how a singlet charged scalar in radiative neutrino mass models can be detected at the LHC through lepton flavor violating trilepton signals, analyzing different channels and energies.

Contribution

It introduces a method to probe neutrino mass models via specific lepton flavor violating signals at the LHC, focusing on the charged scalar interactions.

Findings

Signal channels with opposite sign same flavor leptons are promising.

Tau contributions can significantly enhance signal detection.

Analysis covers both 8 TeV and 14 TeV LHC energies.

Abstract

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.
