Probing Three-Boson Anomalous Couplings in $e^{+}{e}^{-}\to W^{+}{W}^{-}$ at Future Linear $e^{+}{e}^{-}$ Colliders with Polarized Beams

Abstract

We study the potential of the next-generation $e^{+}{e}^{-}$ linear colliders with longitudinally polarized beams, to restrict the values of the anomalous trilinear couplings $WW\gamma$ and $WWZ$ from the measurement of the process $e^{+}{e}^{-}\to W^{+}{W}^{-}$. Along with initial $e^{+}{e}^{-}$ polarization, we account also for the possibilities offered by cross sections for polarized final $W$, in order to disentangle the constraints on the various constants. The results show the essential role of the initial beams polarization in improving the bounds obtained from the unpolarized case.
