Study of single weak boson production in electronpositron scattering
Abstract
The studies of the week boson production in electronpositron scattering are reviewed. At the lowest order of the WeinbergSalam gauge theory, the cross sections for the various processes of the single weak boson production are computed by paying an attention on the gauge invariance at the high energies, or by calculating all the relevant Feynman diagrams, some of which have been neglected in the studies so far. A formulation is presented to compute the cross sections for the various processes, e ^{+} e ^{}→ WUD, where W is the weak boson, WUD stands forW^ + bar U D, orW^  U bar D, and U(D) represents the up (down) state of the SU(2)_{ L } doublet. Also the upper bound of the contributions from the single weak boson production via the two photon process is estimated by using the real photon approximation.
