英文摘要: Continuing the study of boundary BCFW recursion relation of tree level amplitudes initiated in [1], we consider boundary contributions coming from fermion pair deformation. We present the general strategy for these boundary contributions and demonstrate calculations using two examples, i.e, the standard QCD and deformed QCD with anomalous magnetic momentum coupling. To extend BCFW recursion relation to off-shell gluon current, we find a new feature as by-product which comes from the gauge dependence of off-shell gluon currents.
