B-hadrons & Heavy Quarkonium: Spectroscopy & Properties

Abstract

The recent results from the LHC experiments (ATLAS, CMS, and LHCb) are presented in the field of B hadrons and the heavy quarkonium with focus on the properties and the spectroscopy. The observation of the structure in the J/ψϕ mass spectrum, the Λb lifetime measurements and the production of the X(3872) via decays to J/ψπ+π− by CMS experiment will be presented for the first time. Additionally the Bs lifetime difference measurement, observation of χb(3P) state, observation of the excited Λb0 baryons, and the observation of a new baryon Ξb* will be summarized.
