Query: On the Universal Texture in the PA-2HDM for the V-SPIN case   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 $\tau\to\ mu\mu^+\mu^-$
and $\tau\to\gamma\mu$ 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 $B_s\to\mu\mu$ decays,
$B_s^0-\bar{B}_s^0$ mixing, $\tau\to\mu\mu^+\mu^-$ and $\tau\to\gamma\mu$
experimental bounds.
