Precise B, Bs, and Bc meson spectroscopy from full lattice QCD 2011 Access copy available to the general public Unrestricted We give the first accurate results for B and Bs meson masses from lattice QCD including the effect of u, d, and s sea quarks, and we improve an earlier value for the Bc meson mass. By using the highly improved staggered quark (HISQ) action for u=d, s, and c quarks and NRQCD for the b quarks, we are able to achieve an accuracy in the masses of around 10 MeV. Our results are: mB 1/4 5:291ð18Þ GeV, mBs 1/4 5:363ð11Þ GeV, and mBc 1/4 6:280ð10Þ GeV. Note that all QCD parameters here are tuned from other calculations, so these are parameter free-tests of QCD against experiment. We also give scalar, B0s0 and axial-vector, Bs1 meson masses. We find these to be slightly below threshold for decay to BK and B0K, respectively. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.558 2011 PHYSICS, PARTICLES & FIELDS 6 / 27 = 0.222 2011 Q1 T1 ASTRONOMY & ASTROPHYSICS 11 / 56 = 0.196 2011 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Davies, C.T.H.
