Testing QCD with current algebra
Description
Spontaneously broken chiral symmetry fixes the low energy structure of QCD to a large extent. I show how to determine the Green's functions to first nonleading order in a simultaneous expansion in powers of the momenta and of the u- and d-quark masses. In particular, I discuss the corrections of order Mπ2 to the low energy theorems for ππ scattering. 19 refs., 1 tab. (author)
