Measuring the lower bound of the neutrino mass at the LHC in Higgs triplet model

Abstract

We show in the framework of Higgs triplet model that the lower bound of the neutrino mass is obtained if we can measure $\frac{\Gamma ({\Delta }^{--}\to ee)}{\Gamma ({\Delta }^{--}\to \mu \mu )}$ at the LHC.
