  We present preliminary results on the light, charmed and bottom baryon
spectra using overlap valence 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. The SU(2) heavy baryon chiral perturbation theory is used to
extrapolate baryon masses to the physical pion mass and the continuum limit
extrapolations are also performed. Our results are consistent with the well
measured charmed baryons. We predict the masses of many other states which are
yet to be discovered.
