David Lin (Southampton U. | Abstract: | We present results of quenched lattice calculations of the matrix elements relevant for B_d-ar B_d and B_s-ar B_s mixing in the Standard Model. Results for the corresponding SU(3)-breaking ratios, which can be used to constrain or determine |V_{td}|, are also given. The calculations are performed at two values of the lattice spacing, corresponding to eta = 6.0 and eta = 6.2, with quarks described by a mean-field-improved Sheikholeslami-Wohlert action. As a by-product, we obtain the leptonic decay constants of B and D mesons. We also present matrix elements relevant for D^0-ar D^0 mixing. Our results are summarized in the Introduction. | Source: | arXiv, hep-ph/0011086 | Services: | Forum | Review | PDF | Favorites |
