  "abstract": "Two recent observations of new b hadrons in pp collisions at \\sqrt{s} = 7 TeV at the Large Hadron Collider (LHC) are presented. The ATLAS collaboration has observed a new state in radiative transitions to \\Upsilon(1S) and \\Upsilon(2S) and interprets this as the first observation of the \\chi_b(3P) states. The CMS collaboration has observed a new b baryon decaying to \\Xi_b-\\pi+ (plus charge conjugates). This is interpreted as a neutral J^P = 3/2^+ \\Xi_b* baryon.",
