DISCRIMINATING NEW PHYSICS SCENARIOS AT THE NEXT LINEAR COLLIDER - THE ROLE OF POLARIZATION

We explore the potential of the Next Linear Collider, operating in the e gamma mode, to disentangle new physics scenarios in single W produc tion. We study the effects related to the exchange of composite fermio ns in the reaction e gamma-->W nu(e), and compare them with those aris ing from trilinear gauge boson anomalous couplings. We stress the role played by the initial state polarization to increase the reach of thi s machine and to discriminate the possible origin of the new phenomena .
