Query: Analysis of $B_s\to \phi\mu^+\mu^-$ decay within supersymmetry   Motivated by the first measurement on $\mathcal{B}(B_s\to\phi \mu^+\mu^-)$ by
the CDF Collaboration, we study the supersymmetric effects in semi-leptonic
$B_s\to\phi\mu^+\mu^-$ decay. In our evaluations, we analyze the dependences of
the dimuon invariant mass spectrum and the forward-backward asymmetry on
relevant supersymmetric couplings in the MSSM with and without R-parity. The
analyses show the new experimental upper limits of
$\mathcal{B}(B_s\to\mu^+\mu^-)$ from the LHCb Collaboration could further
improve the bounds on sneutrino exchange couplings and $(\delta^u_{LL})_{23}$
as well as $(\delta^d_{LL,RR})_{23}$ mass insertion couplings. In addition,
within the allowed ranges of relevant couplings under the constraints from
$\mathcal{B}(B_s\to\phi \mu^+\mu^-)$, $\mathcal{B}(B\to K^{(*)}\mu^+\mu^-)$ and
$\mathcal{B}(B_s\to \mu^+\mu^-)$, the dimuon forward-backward asymmetry and the
differential dimuon forward-backward asymmetry of $B_s\to\phi\mu^+\mu^-$ are
highly sensitive to the squark exchange contribution and the
$(\delta^u_{LL})_{23}$ mass insertion contribution. The results obtained in
this work will be very useful in searching supersymmetric signal at the LHC.
