Abstract
Our modern understanding of hadrons is of a core of valence quarks surrounded by a sea of \(\bar q\) pairs and gluons. For low energy processes (~ 1 GeV) there is good reason to assume (Witten, 1979; T’Hooft, 1974) that much of the detailed dynamics of the quarks can be neglected and the cloud can be approximated by the correlated, colour neutral \(\bar q\) states that we know as mesons. This is the basis of the success of the meson exchange models of medium energy nuclear physics whose degrees of freedom consist of nucleons, mesons and isobars.
