I present results for the charmed – bottom hadron spectra from lattice calculations using overlap valence quarks (NRQCD formulation for bottom quarks) on the background of 2+1+1 flavours HISQ gauge configurations of the MILC collaboration. These calculations are performed on three different gauge ensembles at three lattice spacings (a ~ 0.12 fm, 0.09 fm and 0.06 fm) and for physical strange, charm and bottom quark masses. Chiral and continuum extrapolated results are compared with the existing numbers from experiments, where applicable. Predictions for the masses of several other states, which are yet to be discovered, will also be presented.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
