چکیده

We discuss some large effects of dynamical fermions. One is a cutoff effect, others concern the contribution of multi-pion states to correlation functions and are expected to survive the continuum limit. We then turn to the preparation for simulations at small lattice spacings which we are planning down to around a = 0.04 fm in order to understand the size of O(a2)-effects of the standard O(a)-improved theory. The dependence of the lattice spacing on the bare coupling is determined through the Schrödinger functional renormalized coupling.

QCD with light Wilson quarks on fine lattices (I): first experiences and physics results

Recent conceptual, algorithmic and technical advances allow numerical simulations of lattice QCD with Wilson quarks to be performed at significantly smaller quark masses than was possible before. Here we report on simulations of two-flavour QCD at sea-quark masses from slightly above to approximately 1/4 of the strange-quark mass, on lattices with up to 64×32 points and spacings from 0.05 to 0....

Perturbative and non-perturbative studies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings

We present a calculation of the O(g2, λ) perturbative corrections to the coupling anisotropies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings. These corrections are obtained by a one-loop calculation requiring the rotational invariance of the gauge and Higgs boson propagators in the continuum limit. The coupling anisotropies are also determined from numerical simulations ...

Chiral perturbation theory for lattice QCD at O(a)

Chiral perturbation theory (χPT) is widely used in analyzing lattice QCD data. Since χPT describes continuum QCD one has to take the continuum limit first before fitting the lattice data to the analytic predictions of χPT. Unfortunately, lattice data for various lattice spacings is often not available in order to perform a reliable continuum extrapolation. Nevertheless, it is common practice to...

Light hadron masses with a tadpole-improved next-nearest-neighbour lattice fermion action

Calculations of hadron masses are done in quenched approximation using gauge field and fermion actions which are both corrected for discretization errors to O(a) at the classical level and which contain tadpole improvement factors. The fermion action has both nearest-neighbour and next-nearestneighbour couplings in the kinetic and Wilson terms. Simulations done at lattice spacings of 0.3 and 0....

Renormalization and O ( a ) - improvement of the static axial current LPHA

A systematic treatment of O(a)–improvement in lattice theories with static quarks is presented. The Schrödinger functional is discussed and a renormalization condition for the static axial current in the SF-scheme is introduced. Its relation to other schemes is computed to 1-loop order and the 2-loop anomalous dimension is derived. In finite volume renormalization schemes such as the SF-scheme,...
