Properties of bottomonia in a relativistic quark model

The mass spectrum of bb̄ states has been obtained using the phenomenological relativistic quark model (RQM). The Hamiltonian used in the investigation has confinement potential and confined one gluon exchange potential (COGEP). In the framework of RQM a study of M1 and E1 radiative decays of bb̄ states has been made. An overall agreement is obtained with the experimental masses and decay widths. The possibility that some of the excited s wave bb̄ states being exotic states is explored.
