Rare two-body meson decays give the strongest current bounds on the ALP-W coupling for light ALPs, with Z-boson decays and future lepton colliders extending the reach to heavier masses.

abstract
In recent years, $B_s$ decays into $tau^+tau^-$ has attracted a lot of attention since it is very sensitive to the structure of standard model (SM) and potential source of new physics beyond SM. In this paper, we study the effect of both Z and -mediated flavor-changing neutral currents on the $B_s$ decays into $tau^+tau^-$. We find the branching ratio of $B_s$ decays into $tau^+tau^-$ is enhanced relative to SM prediction, which would help to explain the recent observed CP-violation from like-sign dimuon charge asymmetry in the B system.
