THE POTENTIAL OF A NEW LINEAR COLLIDER FOR THE MEASUREMENT OF THE TRILINEAR COUPLINGS AMONG THE ELECTROWEAK VECTOR BOSONS

We study the accuracy to be obtained in measuring trilinear Z0W+W- and gammaW+W-couplings in the reaction e+e- --> W+W- at ''New Linear Coll ider'' (NLC) energies of 500 GeV to 1000 GeV. We derive simple scaling laws for the sensitivity in the measurement of these couplings. For m ost couplings the sensitivity increases as square-root L.s, where L de notes the integrated luminosity and square-root s denotes the e+e- cen ter-of-mass energy. Detailed investigations based on various fits conf irm these scaling laws and show that an accuracy of the order of the s tandard radiative corrections can be reached at the NLC for the design values of the luminosity.
