Supersymmetry relations between contributions to one-loop gauge boson amplitudes

Year: 1994

Type: article

Abstract: We apply ideas motivated by string theory to improve the calculational efficiency of one-loop weak interaction processes with massive external gauge bosons. In certain cases "supersymmetry" relations between diagrams with a fermion loop and with a guage boson loop hold. This is explicitly illustrated for a particular one-loop standard model process with four external gauge bosons. The supersymmetry relations can be used to provide further significant improvements in calculational efficiency.
