GENERALIZED RELATIVISTIC MESON WAVE-FUNCTION

We study the most general, relativistic, constituent qqBAR meson wave function within a new co-variant framework. We find that by including a tensor wave function component, a pure valence quark model is now ca pable of reproducing not only all static pion data (f(pi), [r(pi)2]) b ut also the distribution amplitude, form factor [F(pi)(Q2)], and struc ture functions. Purther, our generalized spin wave function provides a much better detailed description of meson properties than models usin g a simple relativistic extension of the S = L = 0 nonrelativistic wav e function.
