摘要：

Full pion four-point functions at zero momentum are calculated with Kogut-Susskind quarks on a 12(3) x 20 lattice at beta=5.7 and m(q)=0.01 in quenched lattice QCD, employing the wall source method without gauge fixing. For both I=0 and 2 channels, results for the s-wave scattering lengths are in agreement with the prediction of current algebra and PCAC (partial conservation of axial-vector current).
