Bottom baryons from a dynamical lattice QCD simulation
arXiv:0806.4783 · doi:10.1103/PhysRevD.79.014502
Abstract
Bottom baryon masses are calculated based on a 2+1 flavor dynamical lattice QCD simulation. The gauge field configurations were computed by the CP-PACS and JLQCD collaborations using an improved clover action. The bottom quark is described using lattice NRQCD. Results are presented for single and double-b baryons at one lattice spacing. Comparison with experimental values is discussed.
