Great effort is presently being expended in the search for elementary scalar “Higgs”
particles. These particles have yet to be observed. The primary justification for this search is …

Over the last few years lattice techniques have been used to investigate candidate theories
of new physics beyond the standard model. This review gives a survey of results from these …

We reconsider the conceptual foundations of the renormalization-group (RG) formalism, and
prove some rigorous theorems on the regularity properties and possible pathologies of the …

There exist lattice actions which give cut-off independent physical predictions even on
coarse grained lattices. Rotation symmetry is restored, the spectrum becomes exact and, in …

We determine the critical couplings for the deconfinement phase transition in SU (2) gauge
theory on N τ× N σ 3 lattices with N τ= 8 and 16 and N σ varying between 16 and 48. A …

The pressure near the deconfinement transition as determined up to now in lattice gauge
theories shows unphysical behaviour: it can become negative and may in SU (3) even have …

We present a Monte Carlo renormalization group study of the SU (2) gauge theory with two
Dirac fermions in the adjoint representation. Using the two-lattice matching technique we …

We present the one-loop (order g 4) perfturbative calculation of the expectation values of
Wilson loops and Polyakov lines on finite asymmetric lattices. Analytical as well as …

In this paper (the first of a series) we describe the construction of fixed-point actions for
lattice SU (3) pure gauge theory. Fixed-point actions have scale-invariant instanton solutions …
