نویسنده
چکیده
We present an investigation of gauge invariant smearing for Wilson fermions on a 24 × 48 lattice at β = 6.2. We demonstrate a smearing algorithm that allows a substantial improvement in the determination of the baryon spectrum obtained using propagators smeared at both source and sink, at only a small computational cost. We investigate the matrix of correlators constructed from local and smeared operators, and are able to expose excited states of both the mesons and baryons.

We propose the study of non-local gauge invariant operators to obtain an uncontaminated ground state for hadrons. The efficiency of the operators is shown by looking at the wave function of the first excited state, which has a node as a function of spatial extent of the operator.

Using an under-relaxed cooling algorithm we investigated the vacuum in the 2d O(3) model and 4d pure gauge SU (2). We calibrated the amount of cooling performed to have similar physical effect at different lattice spacings.

We present some new three-loop results in lattice gauge theories, for the Free Energy and for the Topological Susceptibility. These results are an outcome of a scheme which we are developing (using a symbolic manipulation language), for the analytic computation of renormalization functions on the lattice.

From an accurate determination of the inter-quark potential, one can study the running coupling constant for a range of R-values and hence estimate the scale Λ MS. Detailed results are presented for SU (3) pure gauge theory from a study of a 36 4 lattice at β = 6.5.

We explain why compact U (1) confines and how to fix it. We show that plaquettes of negative trace carry most of the confinement signal in compact SU (2). We show how to perform noncompact gauge-invariant simulations without auxiliary fields. We suggest a way to simulate fermions without doublers.
