Calculating BK using HYP staggered fermions
نویسندگان
چکیده
We give an update on our calculation of BK using HYP-smeared valence staggered quarks. We have results for BK at tree-level on several coarse MILC lattices (a ≈ 0.12fm) and one of the fine lattices (a ≈ 0.09fm), using 10 light valence quarks ranging down to m s /10. We have generalized staggered chiral perturbation theory to our mixed action setup, and outline the results. We explain our present fitting strategy, and give some preliminary results.

Calculating BK using a mixed action
We present preliminary results of B K calculated using improved staggered fermions with the mixed action (valence quarks = HYP staggered fermions and sea quarks = AsqTad staggered fermions). We analyze the data based upon the prediction by Van de Water and Sharpe. A hint of consistency with the prediction is observed. We also present preliminary results of B ¡ 3¢ 2£ 8 and B ¡ 3¢ 2£ 7 .

متن کاملBK in unquenched QCD using improved staggered fermions
We present preliminary results for BK calculated using improved staggered fermions with a mixed action (HYP-smeared staggered valence quarks and AsqTad staggered sea quarks). We investigate the effect of non-degenerate quarks on BK and attempt to estimate the O(a2) effect due to nonGoldstone pions in loops. We fit the data to continuum partially quenched chiral perturbation theory. We find that...
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 (...
متن کاملPion spectrum using improved staggered fermions
We present results for the pion multiplet spectrum calculated using both unimproved staggered fermions and improved HYP-smeared staggered fermions. In the case of unimproved staggered fermions, we observe (consistent with previous work) that O(a2) taste symmetry breaking effects are large and comparable to the ≈ O(p2) contributions to their masses. Higher order O(a2 p2) effects are also substan...
