Charmed baryon spectrum from lattice QCD near the physical point
Bahtiyar, H.; Can, K. U.; Erkol, Güray; Gubler, P.; Oka, M.; Takahashi, T. T. (American Physical Society, 20200923)We calculate the lowlying spectrum of charmed baryons in lattice QCD on the 32(3) x 64, Nf = 2 +/ 1 PACSCS gauge configurations at the almost physical pion mass of similar to 156 MeV/c(2). By employing a set of ...
