Probing Radiative Neutrino Mass Models With Dilepton Events At The LHC

TL;DR

This paper investigates radiative neutrino mass models by analyzing dilepton events with missing energy at the LHC, focusing on lepton flavor violation signals from charged scalar interactions at 8 and 14 TeV.

Contribution

It introduces a method to probe neutrino mass models through specific dilepton final states and emphasizes the importance of the $M_{T2}$ variable for background suppression.

Findings

Effective $M_{T2}$ cuts improve signal detection

Charged scalars could be detectable at LHC energies

Lepton flavor violation signals are promising indicators

Abstract

In this work we prob a class of neutrino mass models at both Large Hadron Collider (LHC) energies 8 TeV and 14 TeV. The focus will be on the new introduced interaction terms between a singlet charged scalar, $S^{\pm}$, and leptons leading to different final states $pp\rightarrow\ell_{\alpha}^{\pm}\ell_{\beta}^{\mp}$ +$\slashed E$ with $\ell_{\alpha}\ell_{\beta}=ee,e\mu,\mu\mu$ that implies lepton flavor violation (LFV). An accurate cut on the $M_{T2}$ eventvariable is found to be crucial for an effective suppression of the large Standard Model background. The obtained results can be translated into a possible detectability of the charged scalars effect..
