Distribution Functions From Breit-Frame Regularisation

Abstract

We suggest a new Hamiltonian lattice approach, using a regularisation motivated by deep inelastic scattering. We discuss the relation between distribution functions and the $F_1$ structure function. We have tested this method by computing the critical behaviour of the scalar model and find agreement with scaling behaviour and with results by Lüscher and Weisz.
