Factorization in processes of graviton scattering off electron for Z and W productions
J. S. Shim, H. S. Song
Abstract
The study of factorization in linearized gravity is extended to the graviton scattering processes with an electron for the massive vector boson productions such as g e → Z e and g e → W νe. It is shown that every transition amplitude is completely factorized due to gravitational gauge invariance and Lorentz invariance. Also the explicit values of vector boson polarizations are obtained.
