S = 2 and ∆ I = 3 / 2 Matrix Elements in Quenched QCD ∗
We report on two, high-statistics, quenched lattice calculations of BK , B 3/2 7 and B 3/2 8 . BK parametrizes theK−K̄-oscillation contribution to CP-violation in K decays (ǫ), leading to a hyperbolic constraint on the summit of the unitarity triangle. B 3/2 7,8 are needed to compute the electropenguin contribution to direct CP-violation (ǫ), dominant in the ∆I = 3/2 channel. BK and B 3/2 7,8 me...
متن کاملQuarkonium Decay Matrix Elements from Quenched Lattice QCD.
The factorization result of Bodwin, Braaten, and Lepage separates the contributions to the decay rates of heavy-quarkonium into long-distance and shortdistance factors. The short-distance coefficients are known from perturbation theory. We calculate the long-distance matrix elements for the lowest-lying Sand P-wave states of charmonium and bottomonium in quenched lattice QCD, using a nonrelativ...
متن کاملCalcutation of kaon matrix elements in quenched domain - wall QCD with DBW 2 gauge action
We give a progress report of our new a −1 ≈ 3 GeV quenched calculation of kaon matrix elements with domain-wall fermion and DBW2 gauge action. Our smaller lattice spacing allows us to address the effect of charmed quark on the lattice. We show preliminary results of BK renormalized non-perturbatively and K → π matrix elements.
متن کاملTransfer Matrix for Partially Quenched QCD
We construct the transfer matrix for the ghost sector of partially quenched QCD. This transfer matrix is not hermitian, but we show that it is still bounded. We thus expect that all euclidean correlation functions will decay exponentially with distance (up to possible powers), and demonstrate that this is indeed the case for free ghost quarks.
