Enhancement of the lepton flavor violating Higgs boson decay rates from SUSY loops in the inverse seesaw model

In this article, we study the full one-loop SUSY contributions to the lepton flavor violating Higgs decay h[arrowright][tau][mu], within the context of the supersymmetric inverse seesaw model. We assume that both the right-handed neutrino masses, M sub()R and their supersymmetric partner masses, m s...

Description
Summary:In this article, we study the full one-loop SUSY contributions to the lepton flavor violating Higgs decay h[arrowright][tau][mu], within the context of the supersymmetric inverse seesaw model. We assume that both the right-handed neutrino masses, M sub()R and their supersymmetric partner masses, m sub([nu])R are not far from the interesting [scriptO](TeV) energy scale, and we work with scenarios with large neutrino Yukawa couplings that transmit large lepton flavor violating effects. By exploring the behavior with the most relevant parameters, mainly M sub()R m sub([nu])Rand the trilinear sneutrino coupling A sub([nu]), we will look for regions of the parameter space where the enhancement of BR(h[arrowright][tau][mu]) is large enough to reach values at the percent level, which could explain the excess recently reported by CMS and ATLAS at the CERN Large Hadron Collider.
