Query: Lepton flavor non-universality in the B-sector: a global analyses of
  various new physics models   The measurements of the ratios $R_{K^{(*)}}$ along with $R_{D^{(*)}}$ hint
towards lepton flavor non universality which is in disagreement with the
standard model. In this work, we reanalyze the four new physics models, which
are widely studied in the literature as a candidates for the simultaneous
explanations of these measurements. These are, standard model like vector boson
(VB), $SU(2)_L$-singlet vector leptoquark ($U_1$), $SU(2)_L$-triplet scalar
leptoquark ($S_3$) and $SU(2)_L$ triplet vector leptoquark ($U_3$) models. We
assume a coupling only to the third generation in the weak basis, so that the
$b \to s \mu^+ \mu^-$ transition is generated only via mixing effects.
Preforming a global fit to all relevant data, we show that the vector boson
model violates the current upper bound on ${Br}(\tau \to 3\mu)$ and hence is
inconsistent with the present data. Further, we show that within this
framework, the $U_1$ leptoquark model cannot simultaneously accommodate
$R_{K^{(*)}}$ and $R_{D^{(*)}}$ measurements. We emphasize that this conclusion
is independent of the additional constraints coming from renormaliztion group
running effects and high-$p_T$ searches. In addition, we show that the $S_3$
and $U_3$ models are highly disfavored by the constraints coming from $b\to s
\nu \bar \nu$ data. Finally, we find a that hypothesis of two LQ particles is
also challenged by $b\to s \bar \nu \nu$ data.
