$B_s$ Decays and Mixing
  Theoretical remarks are offered regarding recent hadron collider results on the mixing and decays of $B_s$ mesons. Topics covered include: (1) CP-violating mixing in $B_s(\ob_s) \to J/\psi \phi$, (2) the D0 dimuon charge asymmetry, (3) information from triple products, (4) $B_s \to J/\psi f_0$, (5) new physics constraints, (6) some illustrative new physics scenarios.
