Description

The low-lying spectrum of charmed baryons is calculated in lattice QCD on the ${32}^3\times 64$, $N_f=2+1$ PACS-CS gauge configurations at the almost physical pion mass of 156 $MeV/c^2$. By employing a set of interpolating operators with different Dirac structures and quark-field smearings for the variational analysis, we extract the ground and first few excited states of the spin-1/2 and spin-3/2, singly-, doubly-, and triply-charmed baryons.
