Search for the anomalous WWγcouplings through the process e−e+→νeνeγat ILC with unpolarized and polarized beams

Abstract

We investigate the anomalous W+W−γcouplings through the process e−e+→νeνeγfor unpolarized and polarized electron (positron) beams at the International Linear Collider. We give the 95%Confidence Level limits on the anomalous couplings with and without the systematic uncertainties for various values of center-of-mass energies and the integrated luminosities. We show that the obtained limits on the anomalous couplings through the process e−e+→νeνeγcan highly improve the current experimental limits.
