Description
We show that bottom-strange production at a high energy muon collider, $\mu^+ \mu^- \to b s$, is a sensitive probe of new physics. We consider the full set of four fermion contact interactions that contribute to this process at dimension 6, and discuss the complementarity of a muon collider and rare $B$ meson decays that probe the new physics.
If a signal were to be found at a muon collider, the forward-backward asymmetry of the $b$-jet provides diagnostics about the underlying chirality structure of the new physics.
In the absence of a signal at a center of mass energy of $10$~TeV, $\mu^+ \mu^- \to b s$ can indirectly probe new physics scales as large as $86$~TeV. We also discuss the impact that beam polarization has on the muon collider sensitivity.
