The $(b, c, s)$ quarks are physical, while the $(u, d)$ quarks are heavier than their physical masses, with the pion mass $ \\sim 700 $ MeV. The gauge ensemble is generated by hybrid Monte Carlo simulation with the Wilson gauge action for the gluons, and the optimal domain-wall fermion action for the quarks. Using point-to-point quark propagators, we measure the time-correlation functions of quark-antiquark meson interpolators with quark contents $\\bar b b$, $\\bar b c$, $\\bar b s$, and $ \\bar c c$, and obtain the masses of the low-lying mesons. They are in good agreement with the experimental values, plus some predictions which have not been observed in experiments. Moreover, we also determine the masses of $(b, c, s)$ quarks.", "revisions": [ { "version": "v1", "updated": "2020-04-05T10:14:39.000Z" } ], "analyses": { "keywords": [ "exact chiral symmetry", "lattice qcd", "beauty mesons", "hybrid monte carlo simulation", "optimal domain-wall fermion action" ], "note": { "typesetting": "TeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable" } } }
