Abstract: We give the first accurate results for B and B_s meson masses from lattice QCD including the effect of u, d, and s sea quarks, and we improve an earlier value for the B_c 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: m_B=5.291(18) GeV, m_Bs=5.363(11) GeV, and m_Bc=6.280(10) 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, B_s0* and axial-vector, B_s1 meson masses. We find these to be slightly below threshold for decay to BK and B*K, respectively.
