Abstract

We generalize the assumptions of the parton model to include the possibility of scale-invariant short-distance behavior. A physical picture is used to motivate our formal equations. Bjorken scaling is violated in a systematic way. We compute the asymptotic properties of νW2 and show that its moments are power-behaved functions of Q2. Arguments are presented for a nonzero value of σSσT in the deep-inelastic limit. The asymptotic behavior of electromagnetic form factors is found to be (Q2)a, where the constant a is related to properties of νW2.
