Width difference of the Bs mesons from lattice QCD
We extend our previous studies to calculate the B meson B parameters BB and BS on the lattice, and present an update of the results for the Bs meson width difference. We perform an extensive study of systematic errors in the quenched calculation of the B-parameters, and find that the systematic errors are in good control using the NRQCD action for heavy quark. We also report our preliminary res...
متن کاملHybrid mesons from lattice QCD
Recent lattice simulation studies of heavy-quark hybrid mesons in which the quark and antiquark are bound together by an excited gluon field are summarized. Hybrid mesons are states in which a valence quark and an antiquark are bound by an excited gluon field. Interest in such states has been recently sparked by observations of resonances with exotic 1 quantum numbers[1]. In fact, the proposed ...

متن کاملMesons at large Nc from lattice QCD
We calculate the pion and ρ meson masses in quenched SU(N) gauge theories for N = 2, 3, 4 and 6. Extrapolating these results to the chiral and large-N limits, we find mρ = (1.670± 0.024) √ σ = (741± 11) MeV for the ρ meson mass at a fixed lattice spacing a ≈ 0.093 fm. We estimate a continuum value, mρ = (786 ± 22) MeV, where we use the value σ = 1 GeV/fm ≈ (444 MeV) for the string tension. We f...
متن کاملBs Mesons in the MSSM with R-parity Violation
Motivated by the possible large direct CP asymmetry of B̄0 d → D + D − decay measured by Belle collaboration, we investigate double charm Bu,d and Bs decays in the minimal supersymmetric standard model with R-parity violation. We derive the bounds on relevant R-parity violating couplings from the current experimental data, which show quite consistent measurements among relative collaborations. U...
