Description
In this work we use a parametrization of Yukawa matrices of the 2HDM-III using invariant subgroups of SU(3) in order to reduce the number of free parameters of the model. It is shown how the flavour violating couplings of leptons are naturally suppressed as expected. We will show explicit relations of the parameters of the SU(3) with the parameters of the 2HDM-III with Cheng and Sher textures. Using bounds on tau decays with production of pseudoscalar mesons, we give some possible values of free parameters of the such SU(3)transformations.
