Study of the anomalous couplings at NLC with polarized beams

Abstract

The present contribution reports a study of the effects of anomalous gauge and fermionic couplings in the process $e^{+}{e}^{-}->W^{+}{W}^{-}$ at the Next Linear Collider focusing in particular on the option of polarized beams. We conclude that polarized beams with adjustable degree of polarization would constitute a very significant tool in the search for new physics.
