4.1 LFV H Decays in the ISS Model

LFV Higgs decay rates within the SM with new heavy Majorana neutrinos were first studied in Refs. [52–54]. In this Section, we analyze these rates in the context of the ISS model with three pairs of fermionic singlets added to the SM, and fully study their one-loop contributions to the LFVHD rates. As we did for the LFV radiative decays in the previous Chapter, we use the two parametrizations introduced in Sect. 2.​3, the Casas-Ibarra and the parametrization, to explore these LFVHD rates and discuss the main differences of using one parametrization versus the other.
