The Parton Model and Asymptotic Freedom Revisited

  • Geoffrey B. West
Part of the Ettore Majorana International Science Series book series (EMISS, volume 5)


It is the intent of these lectures to give a retrospective review of some of the salient features of the parton model and its relationship to light cone dynamics and asymptotic freedom. There are, of course, many excellent review articles1 covering these topics so in order to avoid excessive repetition I shall attempt to dwell on various aspects of the problem from a somewhat different perspective than usual.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
