Signal of h → µτ, ττ in ν2HDM⊕S3

Abstract

Nowadays in particle physics, the exploration of the flavor physics through the Higgs boson phenomenology is one of the main goals in the field. In particular we are interested in the Lepton Flavour Violation (LFV) processes. In this work, we explore the processes h → µτ, ττ in the theoretical framework of a flavored extension of the Standard Model, which has two Higgs fields and the horizontal permutation symmetry S3 imposed in the Yukawa sector, this extension is called v2HDM⊗S3.We obtain the couplings Φµτ, ττ as well as Br(h → µτ) in function of the model parameters in function of the model parameters, which are constricted by means the experimental results of ΦMS → µτ reported in the literature
