Determination of the unknown absolute neutrino mass and MNS parameters at the LHC in the Higgs triplet model

TL;DR

This paper explores how measurements of doubly charged Higgs decays at the LHC can determine the absolute neutrino mass and MNS parameters within the Higgs triplet model, considering CP phases.

Contribution

It provides a method to constrain neutrino properties and CP phases using collider data in the Higgs triplet model, a novel approach in neutrino physics.

Findings

Constraints on MNS parameters and CP phases

Impact of Majorana CP phases on predictions

Abstract

Assuming the Higgs triplet model, we obtain the bounds on the absolute neutrino mass and the unknown MNS parameters by measuring decay processes of doubly charged particles at the CERN LHC. Majorana CP violating phases affect the prediction rather seriously, which is served to restrict these phases.
