摘要：We perform the first study of treating b, c, and s quarks as Dirac fermions in lattice QCD with exact chiral symmetry. On a 323 ×60 lattice with a−1 ≃ 7.68 GeV, we compute point-to-point quark propagators, and measure the time-correlation functions for mesons with quark contents b¯b, c¯b, s¯b, and c¯c. The lowest-lying meson mass spectra, the pseudoscalar decay constants, and the b and c quark masses are determined.
