“…It was proceed to compare the behavior of (38) using two cases; the diagonal case represented by the expression (37) and the parallel case where the mixing matrix is written with one zero texture for both the charged lepton sector and neutrino sector.…”

“…As a consequence we can explore the possibility of a Universal Texture Constraint (UTC) as described in [17] for the Yukawa sector in extended scalar models, but in this case for the SM. The UTC was introduced in [37] to reduce drastically the number of free parameters in models with parallel textures.…”

“…In the case when there exist mixing only between second and third generation, the only observable that might be deviated from the SM prediction is ∆M B 0 s . In our previous work, 7 we have shown that it is possible to find a bound on the non standard scalar contribution to this observable assuming that the experimental measurement contains two terms of the form…”

In a Partially Aligned Two Higgs Doublet Model, where only is allowed flavor violation between third and second generation of fermions, we propose a mechanism to generate the second Yukawa matrix through a Unitary V-Spin flavor transformation on the mass matrix for quarks and leptons. Also we assume that this flavor transformation is universal, this is, we use the same parameters to generate Yukawa matrix elements in both sectors, reducing drastically the number of free parameters. As consequence we obtained a serie of relations between Yukawa matrix elements, that we called the Universality Constraint. Also, we obtained an interval of values for the second Yukawa matrix elements, expressed in terms of the Cheng and Sher ansatz, for τ → µµ + µ − and τ → γµ coming from the Universality Constraint and experimental bounds for light scalar masses. Finally, we show the allowed region of parameters for the flavor transformation from Bs → µµ decays, B 0 s − B0 s mixing, τ → µµ + µ − and τ → γµ experimental bounds.

In a version of the PA-2HDM where only mixing between third and second fermion generations is allowed, we propose a mechanism to generate the second Yukawa matrix through a Unitary V-spin flavor transformation on the mass matrix for quarks and leptons. This flavor structure is constrained to be universal, that is, we use the same parameters to generate Yukawa matrix elements in the quark and leptonic sectors, reducing drastically the number of free parameters of the PA-2HDM. As a consequence of this restrictive condition, we obtain relations between the Yukawa matrix elements, that we call the Universal Texture Constraint (UTC). We obtained an interval of values for the second Yukawa matrix elements, expressed in terms of the Cheng and Sher ansatz, for [Formula: see text] and [Formula: see text] coming from the UTC and experimental bounds for light scalar masses. Finally, we find the allowed parameter region when the experimental bounds and values for [Formula: see text] decays, [Formula: see text] mixing, [Formula: see text] and [Formula: see text] are considered.
