BK from the lattice with Wilson quarks
نویسنده
چکیده
We report our results for the bag-parameter BK obtained from the quenched simulations on the lattice with Wilson fermions at three values of the lattice spacing. We implemented the method by which no subtraction of the mixing with other fourfermion ∆S = 2 operators is needed. Our final result, in terms of the renormalisation group invariant bag-parameter, is B̂K = 0.96 ± 0.10. PACS: 11.15.Ha, 12.38.Gc, 13.25.Hw, 13.25.Jx, 13.75Lb, 14.40.-n.

A lattice QCD calculation of the kaon B parameter BK is carried out with the Wilson quark action in the quenched approximation at β = 6/g2 = 5.9− 6.5. The mixing problem of the ∆s = 2 four-quark operators is solved nonperturbatively with full use of chiral Ward identities employing four external quarks with an equal off-shell momentum in the Landau gauge.

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 کاملHadronic Matrix Elements from the Lattice A
Lattice matrix elements are briefly reviewed. In the quenched approximation fB, BB and BK are now under good control. Experimental hints for f expt DS > f DS are noted; precise determination of fDS from experiment as well as from the lattice is strongly advocated. Lattice calculations of the form factor for B → πlν at relatively large value of q have made good progress and should be useful in c...
متن کاملScaling and low energy constants in lattice QCD with Nf = 2 maximally twisted Wilson quarks
We report on the scaling of basic hadronic observables in lattice QCD with N f = 2 maximally twisted Wilson dynamical quarks. We give preliminary results for some of the Gasser–Leutwyler low energy constants, the chiral condensate and the average mass of u and d quarks.
