Factorization in processes of a graviton scattering off an electron for Z and W production.

The study of factorization in linearized gravity is extended to the graviton scattering processes with an electron for massive vector boson production such as {ital ge}{r_arrow}{ital Z}{ital e} and {ital ge}{r_arrow}{ital W}{nu}{sub {ital e}}. It is shown tha t every transition amplitude is completely factorized due to gravitational gauge invariance and Lorentz invariance. Also the explicit values of vector boson polarizations are obtained. {copyright} {ital 1996 The American Physical Society.}
