  The long persistent discrepancies in $b\,\to\,s\, \ell\, \ell$ quark level
transitions continue to be the ideal platform for an indirect search of new
physics that lies beyond the SM. The measurements of $R_K$, $R_{K^*}$,
$P_5^{\prime}$, $\mathcal{B}(B_s\, \to\, \phi\, \mu^+\,\mu^-)$ and
$\mathcal{B}(B_s\, \to\, \mu^+\,\mu^-)$ persistently deviate from the standard
model expectations. Similarly, the new tests of lepton flavor universality
performed using the isospin partners such as $B^0 \, \to \, K_S^{0} \,
\ell\,\ell$ and $B^+ \, \to \, K^{+*} \, \ell\,\ell$ exhibit the same pattern
of deviation in $R_{K_S^0}$ and $R_{K^{*+}}$ with the existing results.
Motivated by these anomalies we search for the patterns of new physics in the
family of flavor changing neutral decays with neutral leptons in the final
state undergoing $b \, \to \,s\, \nu \, \bar{\nu}$ quark level transitions.
There are close relations between $b\,\to\,s\, \ell\, \ell$ and $b \, \to \,s\,
\nu \, \bar{\nu}$ transitions not only in standard model but also in various
beyond the standard model scenarios. For beyond the standard model physics
under the $\rm SU_L(2)$ gauge symmetry one can relate the left handed charged
leptons to the neutrinos. Moreover, there are several advantages of studying $b
\, \to \,s\, \nu \, \bar{\nu}$ transitions over $b\,\to\,s\, \ell\, \ell$ as
they are free from various hadronic uncertainties beyond the form factors such
as the non-factorizable corrections and photonic penguin contributions. Hence,
we explore the consequences of $b\, \to\, s\, \mu^+\, \mu^-$ anomalies on $B \,
\to \, K^{(*)} \,\nu \, \bar{\nu}$, $B_s \to\, (\eta,\eta') \, \nu\,\bar{\nu}$
and $B_s \, \to \, \phi \, \nu \, \bar{\nu}$ decay observables in SMEFT
platform within various 1D and 2D new physics scenarios.
