The Kaon B-Parameter in Staggered Chiral Perturbation Theory
Ruth S. Van de Water, Stephen R. Sharpe
We calculate the kaon B-parameter, B_K, to next-to-leading order in staggered chiral perturbation theory. We extend the usual power counting to include the effects of using perturb…
Improved bilinears in unquenched lattice QCD
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +2
We summarize the extent to which one can use Ward identities to non-perturbatively improve flavor singlet and non-singlet bilinears with three flavors of non-degenerate dynamical W…
Progress report on the staggered epsilon'/epsilon project
T. Bhattacharya, G. T. Fleming, G. Kilcup +3
We report on progress and future plans for calculating kaon weak matrix elements for epsilon'/epsilon using staggered fermions.
Order a improved renormalization constants
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +1
We present non-perturbative results for the constants needed for on-shell improvement of bilinear operators composed of Wilson fermions. We work at and 6.2 in the qu…
Non-perturbative improvement of bilinears in unquenched QCD
T. Bhattacharya, R. Gupta, W. Lee +1
We describe how the improvement of quark bilinears generalizes from quenched to unquenched QCD, and discuss which of the additional improvement constants can be determined using Wa…
Order a improved renormalization constants
T. Bhattacharya, R. Gupta, W. Lee +1
We impose the axial and vector Ward identities on local fermion bilinear operators in the Sheikholesalami-Wohlert discretization of fermions. From this we obtain all the coefficien…
