Intrinsic short-distance structure of hadrons in QCD

摘要

A central problem of particle physics is to determine the composition of hadrons in terms of their fundamental quark and gluon degrees of freedom. The structure of hadronic bound-states in quantum chromodynamics plays a role in virtually every aspect of high energy and weak interaction phenomenology, including jet hadronization, heavy particle production processes at colliders, general exclusive and inclusive reactions, and electro-weak decay matrix-elements. Although the QCD Lagrangian has an elegant simplicity, the structure of its bound state solutions can be extraordinarily rich and complex. In these lectures I will focus on QCD phenomena which reflect the coherence and composition of hadron wave functions as relativistic many--body systems of quark and gluon quanta. 83 refs.
