摘要：
The Cachazo-Svrcek-Witten (CSW) rule for efficiently calculating gauge theory amplitudes is extended to N=1 supersymmetric QCD (SQCD), incorporating massless quarks, in a manner that preserves the manifest supersymmetry. Using this extended CSW rule, we obtain compact expressions for all the one-loop MHV amplitudes in SQCD including one or two external quark-antiquark (chiral-antichiral multiplets) pairs. The collinear singularities of the five-point amplitudes are investigated to confirm the consistency of the results.
