Testing asymptotically free quarks (e/sup +/e/sup -/ to hadrons)
It is shown that asymptotic freedom permits one to calculate not only the hadronic contributions to the photon propagator Phi (q/sup 2/) in the space-like region, but also the derivatives delta /sup n/ Phi (q /sup 2/)/ delta (q/sup 2/)/sup n/. From this is obtained a set of rigorous upper and lower...
