Query: Phenomenology of the Partially Aligned 2HDM with leptonic decay of
  mesons   In this paper we present a phenomenological analysis of the Partially Aligned
Two Higgs Doublet Model (PA-2HDM) by using leptonic decays of mesons and
$B^0_{d,s}$-$\bar B^0_{d,s}$ mixing. We focus our attention in a scenario where
the leading contribution to FCNC is given by the tree level interaction with
the light pseudoscalar $A^0$ ($M_{A^0}\sim 250$ GeV). We show how an underlying
flavor symmetry controls FCNC in the quark and lepton couplings with the
pseudoscalar, without alignment between Yukawa matrices. Upper bounds on the
free parameters are calculated in the context of the leptonic decays
$B^0_{s,d}\to\mu^+\mu^-$ and $K^0_L\to \mu^+\mu^-$ and $B^0_{s,d}$ mixing.
Also, our assumptions implies that bounds on New Physics contribution in the
quark sector coming from $B^0_{s,d}$ mixing impose an upper bound on the
parameters for the leptonic sector. Finally we give predictions of branching
ratios for leptonic decay of mesons with FCNC and LFV.
