Charmed baryon spectroscopy from lattice QCD near the physical point

物理点付近の格子QCDによるチャーム・バリオン分光

Gubler, P. 

Gubler, P.

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.
