Quantum Numbers of Recently Discovered Ωc0 Baryons from Lattice QCD

Quantum Numbers of Recently Discovered Ωc0 Baryons from Lattice QCD We present the ground and excited state spectra of Ωc0 baryons with spin up to 7/2 from lattice quantum chromodynamics with dynamical quark fields. Based on our lattice results, we predict the quantum numbers of five Ωc0 baryons, which have recently been observed by the LHCb Collaboration. Our results strongly indicate that the observed states Ωc(3000)0 and Ωc(3050)0 have spin-parity JP=1/2-, the states Ωc(3066)0 and Ωc(3090)0 have JP=3/2-, whereas Ωc(3119)0 is possibly a 5/2- state. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review Letters American Physical Society (APS)
