چکیده
Last year Collins, Edwards, Heller, and Sloan [1] studied heavy Wilson quarks [2] with the improved action of Sheikholeslami and Wohlert [3]. In lattice units the heavy-quark mass mQa typically exceeded unity, a regime in which the numerical results require a nonrelativistic interpretation [4,5] just as in NRQCD [6,7]. Ref. [1] presents a test of the nonrelativistic interpretation that removes kinematic effects and focuses on a dynamical effect—the binding energy. The results of this test were unexpectedly anomalous. The aim of this paper is to explain why and to offer a remedy. Let us begin with some basics to define notation. As a function of momentum p the energy of a state X can be written

We report on some attempts to use lattice QCD to investigate topics in strong interaction phenomenology which are usually interpreted in terms of soft Pomeron exchange.

The importance of lattice gauge field interpolation for our recent non-perturbative formulation of chiral gauge theory is emphasized. We illustrate how the requisite properties are satisfied by our recent four-dimensional non-abelian interpolation scheme, by going through the simpler case of U (1) gauge fields in two dimensions.

We present results for the spectrum and decay constants of B mesons from NRQCD using dynamical configurations at β = 5.6 with two flavours of staggered fermions. The light quarks are generated using the Clover action with tadpole improvement.

We discuss the application of the MPSTV non-perturbative method [1] to the operators relevant to kaon decays. This enables us to reappraise the long-standing question of the ∆I = 1/2 rule, which involves power-divergent subtractions that cannot be evaluated in perturbation theory. We also study the mixing with dimension-six operators and discuss its implications to the chiral behaviour of the B...

It is shown that the binding effect that is associated with the short range part of the Goldstone boson exchange interaction between constituent quarks provides a good description of the πN σ-term.
