Non-degenerate quark mass effect on BK in the mixed action
نویسندگان
چکیده
We investigate the effect of non-degenerate quarks on BK . This effect is noticeably large for BK (significantly larger than statistical uncertainty). Hence, it is important to include this effect in order to determine BK with higher precision. We also observe that the quality of fitting for BK gets better when we include non-degenerate combinations to fit to the prediction by Van de Water and Sharpe. However, this effect on B 7 and B (3/2) 8 turns out to be relatively small.

BK 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 کاملThe role of BK channels in antiseizure action of the CB1 receptor agonist ACEA in maximal electroshock and pentylenetetrazole models of seizure in mice
The anticonvulsant effect of cannabinoid compound has been shown in various models of seizure. On the other hand, there are controversial findings about the role of large conductance calcium-activated potassium (BK) channels in the pathogenesis of epilepsy. In this study, the effect of arachidonyl-2′-chloroethylamide (ACEA), a CB1 receptor agonist, and a BK channel antagonist, paxilline, either...

متن کاملA 1993 Look at the Lower Bound on the Top Quark Mass from CP Violation
We point out that the lower bound on mt from the CP violation parameter ǫK has increased considerably. Using Wolfenstein parametrization of the CKM matrix we derive an analytic expression for this bound as a function of | Vcb |, | Vub/Vcb | and the non-perturbative parameter BK . For BK ≤ 0.80, | Vcb |≤ 0.040 and | Vub/Vcb |≤ 0.10 we find mt > 130GeV . However, for BK ≤ 0.70, | Vcb |≤ 0.038 and...
متن کاملKaon B Parameter from Quenched Domain-wall Qcd * Cp-pacs Collaboration : A
We report on a calculation of BK with domain wall fermion action in quenched QCD. Simulations are made with a renormalization group improved gauge action at β = 2.6 and 2.9 corresponding to a ≈ 2GeV and 3GeV. Effects due to finite fifth dimensional size N5 and finite spatial size Nσ are examined in detail. Matching to the continuum operator is made perturbatively at one loop order. We obtain BK...
