Review of Bs mesons and b Baryons
  The measurements of B_s mesons and b baryons advanced greatly in the past year. The ground state b baryon Xi_b^0 was observed for the first time; numerous decay modes of the B_s^0 and b baryons were newly seen; measurements of CP violation in B_s^0 decays were improved, generally improving the agreement with the standard model; and the search for rare decays sensitive to new physics were pushed to new levels. It was a very productive year for measurements of b baryons and B_s^0 mesons.
