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 capable of reproducing not only all static pion data (f(pi), [r(pi)2]) but also the distribution amplitude, form factor [F(pi)(Q2)], and structure functions. Purther, our generalized spin wave function provides a much better detailed description of meson properties than models using a simple relativistic extension of the S = L = 0 nonrelativistic wave function.
