The Critical Hopping Parameter in O(a) improved Lattice QCD
We calculate the critical value of the hopping parameter, κc, in O(a) improved Lattice QCD, to two loops in perturbation theory. We employ the Sheikholeslami-Wohlert (clover) improved action for Wilson fermions. The quantity which we study is a typical case of a vacuum expectation value resulting in an additive renormalization; as such, it is characterized by a power (linear) divergence in the ...
متن کاملKaon B parameter from quenched Lattice QCD
We present results of a large-scale simulation for the Kaon B parameter BK in quenched lattice QCD with the Kogut-Susskind quark action. Calculating BK at 1% statistical accuracy for seven values of lattice spacing in the range a ≈ 0.24 − 0.04 fm on lattices up to 563 × 96, we verify a quadratic a dependence of BK theoretically predicted. Strong indications are found that, with our level of acc...
متن کاملLattice QCD : a critical status report
The substantial progress that has been achieved in lattice QCD in the last years is pointed out. I compare the simulation cost and systematic effects of several lattice QCD formulations and discuss a number of topics such as lattice spacing scaling, applications of chiral perturbation theory, non-perturbative renormalization and finite volume effects. Additionally, the importance of demonstrati...

متن کاملA Determination of the Lambda Parameter from Full Lattice QCD
We present a determination of the QCD parameter Λ in the quenched approximation (nf = 0) and for two flavours (nf = 2) of light dynamical quarks. The calculations are performed on the lattice using O(a) improved Wilson fermions and include taking the continuum limit. We find Λ nf=0 = 259(1)(20)MeV and Λ nf=2 = 261(17)(26)MeV, using r0 = 0.467 fm to set the scale. Extrapolating our results to fi...
