Properties of ground state pseudo scalar and vector $c\bar{b}$ states in   a relativistic quark model
  The phenomenological relativistic quark model (RQM) has been employed to obtain the masses of ground state pseudo scalar and vector $c\bar{b}$ states. In the frame work of RQM a study of M1 radiative decays of $c\bar{b}$ has been made. The Hamiltonian used in the investigation has confinement potential and confined one gluon exchange potential (COGEP). An overall agreement is obtained with the experimental masses and decay widths. Calculated values are compared with other theoretical models.
