Covariance of Light - Front Models : Pair Current

Abstract

We compute the + component, i.e., j + = j 0 + j 3 , of the electromagnetic current of a composite spin-one two-fermion system for vanishing momentum transfer component q + = q 0 + q 3. In particular, we extract the nonvanishing pair production amplitude on the light-front. It is a consequence of the longitudinal zero momentum mode, contributing to the light… (More)
