Description
We present preliminary results on the ground state spectra of singly- charmed, singly-bottomed and doubly heavy charmed-bottom baryons using overlap valence quarks on the background of 2+1+1 flavours HISQ gauge configurations of MILC collaboration. These calculation are performed at three lattice spacings and for physical strange, charm and bottom quark masses. We perform chiral and continuum extrapolations of ground states masses of these heavy baryons from results obtained at three different lattices. Our results are consistent with the experimentally measured masses of various heavy baryons where data are available. In addition we predict the masses of many other heavy baryons which could possibly be discovered in near future.
