Search for the anomalous $WW\gamma$ couplings through the process $e^{-}{e}^{+}\to {\nu }_e{\bar{\nu }}_e\gamma$ at ILC with unpolarized and polarize beams

Abstract

We investigate the anomalous $W^{+}{W}^{-}\gamma$ couplings through the process $e^{-}{e}^{+}\to {\nu }_e{\bar{\nu }}_e\gamma$ for 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 $e^{-}{e}^{+}\to {\nu }_e{\bar{\nu }}_e\gamma$ can highly improve the current experimental limits.
