Inverted neutrino mass hierarchy and new signals of a chromophobic charged Higgs at the Large Hadron Collider

TL;DR

This paper investigates a unique charged Higgs signal at the LHC within a two Higgs doublet model featuring an inverted neutrino mass hierarchy, highlighting its leptonic decay signatures due to suppressed quark couplings.

Contribution

It introduces a novel leptonic signature of a chromophobic charged Higgs in a specific two Higgs doublet model with inverted neutrino hierarchy, expanding potential detection channels.

Findings

Charged Higgs has negligible quark couplings, dominant leptonic interactions.

Distinctive signals involve electrons and muons with missing energy.

Potential for new detection strategies at the LHC.

Abstract

We explore the signals of a charged Higgs arising in a two Higgs doublet model respecting SU(2)_L times U(1) times Z_2 symmetry with three singlet right handed neutrinos, N_R. The charged Higgs in this model has negligible coupling with quarks, and has unsuppressed coupling to leptons and neutrinos. This leads to novel signatures of the charged Higgs at the LHC, especially in the case of an inverted neutrino mass hierarchy, in the form of electrons and muons with missing energy.
