Probing the Light Sterile Neutrino Through the Heavy Charged Higgs Decay on the LHC

TL;DR

This paper investigates the potential to detect light sterile neutrinos via heavy charged Higgs decays at the 13 TeV LHC, using collider simulations within a $ u$-two-Higgs-doublet-model to identify distinctive signals.

Contribution

It introduces a novel collider simulation approach for probing light sterile neutrinos through heavy charged Higgs decay channels in a $ u$-THDM framework.

Findings

Heavy charged Higgs bosons can be produced and decay into sterile neutrinos.

Sterile neutrino decays produce jet-like objects with muons, aiding signal discrimination.

Simulation results suggest feasible detection strategies at the LHC.

Abstract

We show the 13 TeV proton-proton collider simulation in a $\nu$-two-Higgs-doublet-model ($\nu$-THDM). The heavy charged Higgs bosons are produced in pairs through the electroweak processes and decay to the light sterile neutrinos. The light sterile neutrino further decays into a jet-like object with a muon in it. This helps us discriminate the signal from the backgrounds with the standard model jets.
