Electromagnetic structure of W ± bosons in the e – e + → W + W – reaction

Abstract

A model-independent analysis of anomalous gauge coupling constants of W ± bosons is presented and the corresponding restrictions on them and on the electromagnetic characteristics of W ± bosons following from the experiments on measuring the $ {e^{+} }{e^{-} } \to {W^{+} }{W^{-} } \to \left( {{{e} \left/ {{\mu, \bar{v}}} \right.}} \right) \oplus \left( {q,\bar{q}} \right) $ process on the e + e − International Linear Collider are obtained. The method of obtaining the model-independent restrictions on the anomalous gauge constants is based on the use of the polarization scattering cross sections for different initial and final polarization states.
