Probing Radiative Neutrino Mass Models with Dilepton Events at the LHC

Understand

In this work, we investigate the possibility of probing a class of neutrino mass models at the LHC proton-proton collisions with 8 and 14 TeV energies.

• The existence of lepton flavor violating interactions for a singlet charged scalar, $S^{\pm}$, that couples to the leptons could induce many processes such as $pp\rightarrow\ell_{\alpha}^{\pm}\ell_{\beta}^{\mp}+\slashed E $.
• Using the processes with $\ell_{\alpha}\ell_{\beta}=ee,e\mu,\mu\mu$, we found that an inclusive cut on the $M_{T2}$ event variable is vital in our analysis and leads to an effective suppression of the large Standard Model background.
• Our results show possible detectability of the charged scalars effect, especially at the $\sqrt{s}= 14~\text{TeV}$.
