Abstract

These lectures were supposed to serve as an introduction to the parton model and ideas associated with asymptotic freedom which could then be used freely by later speakers. To keep the attention of those to whom it was already familiar, I decided that while introducing the parton model, I would attempt simultaneously to review all its applications to processes involving leptons. It turned out that the introduction was probably too compressed for the uninitiated and the review covered too many topics too quickly to be followed easily. However, I hope that the written version of this “introductory review”, which is contained in part I of these notes, will prove useful.

    An investigation of the choice of scaling variable, the correct combinations of structure functions to which the predictions apply and the higher orders in αs is obviously especially important in the case of FL.
