چکیده
The advantage of this action is that the Dirac operator remains non-singular when m = 0 so that we can work in the chiral limit. Note that we have an exact chiral symmetry generated by γ5ξ5 which means we will have a massless pion at m = 0 when this symmetry is spontaneously broken. The 4-fermion term is an irrelevant operator, so this theory should have the same continuum limit — continuum QCD — as the standard action.

We present an exact local bosonic algorithm for the simulation of dynamical fermions in lattice QCD. We show that this algorithm is a viable alternative to the Hybrid Monte Carlo algorithm.

We present high-statistics results for neutral B-meson mixing and heavy-light-meson leptonic decays in the quenched approximation from tadpole-improved clover actions at β = 6.0 and β = 6.2. We consider quantities such as BBd(s) , fDd(s) , fBd(s) and the full ∆B = 2 matrix elements as well as the corresponding SU(3)-breaking ratios. These quantities are important for determining the CKM matrix ...

We present results of an ongoing study of two flavour QCD with Wilson fermions at finite temperature. We have used tree level Symanzik improvement in both the gauge and fermion part of the action. The phase diagram was previously determined on an 8 3 × 4 lattice and the existence of Aoki's phase demonstrated. On our current lattice of 12 2 × 24 × 4 we have extended the set of observables and st...
