Staggered fermion matrix elements using smeared operators
We investigate the use of two kinds of staggered fermion operators, smeared and unsmeared. The smeared operators extend over a 44 hypercube, and tend to have smaller perturbative corrections than the corresponding unsmeared operators. We use these operators to calculate kaon weak matrix elements on quenched ensembles at β = 6.0, 6.2 and 6.4. Extrapolating to the continuum limit, we find BK(NDR,...
متن کاملImprovement of the Staggered Fermion Operators
We present a complete and detailed derivation of the finite lattice spacing corrections to staggered fermion matrix elements. Expanding upon arguments of Sharpe, we explicitly implement the Symanzik improvement program demonstrating the absence of order a terms in the Symanzik improved action. We propose a general program to improve fermion operators to remove O(a) corrections from their matrix...
متن کاملPerturbative Corrections for Staggered Four-fermion Operators
We present results for one-loop matching coefficients between continuum fourfermion operators, defined in the Naive Dimensional Regularization scheme, and staggered fermion operators of various types. We calculate diagrams involving gluon exchange between quark lines, and “penguin” diagrams containing quark loops. For the former we use Landau gauge operators, with and without O(a) improvement, ...
متن کاملMatrix elements of four-fermion operators in the HQET
The B-B̄ mixing, B-meson lifetimes, the Bs-B̄s lifetime difference and SUSY FCNC effects in ∆B = 2 processes are very important measurable quantities in B-meson phenomenology whose theoretical predictions depend on unknown matrix elements of several four–fermion operators. We present preliminary results for the matrix elements of the relevant four–fermion operators computed on a sample of 600 lat...
متن کاملRecent progress in calculating weak matrix elements using staggered fermions
We present a chronological review of the progress in calculating weak matrix elements using staggered fermions. We review the perturbative calculation of one-loop matching formula including both current-current diagrams and penguin diagrams using improved staggered fermions. We also present preliminary results of weak matrix elements relevant to CP violation calculated using the improved (HYP (...
