CP-violating Anomalous $WW\gamma$ Couplings in e^+e^- Collisions

Abstract

We investigate the sensitivity of future linear collider experiments to CP violating $WW\gamma$ couplings in the process $e^{+}{e}^{-}\to \nu \bar{\nu }\gamma$. We consider several sets of machine parameters: centre of mass energies $\sqrt{s}$ = 350, 500 and 800 GeV and operating at different luminosities. From an analysis of the differential cross-section the following 95% C.L. limits $|{\tilde{\kappa }}_{\gamma }|<0.18$, $|{\tilde{\lambda }}_{\gamma }|<0.069$ are estimated to be obtained at a future 500 GeV LC with an integrated luminosity of $125 \fb^{-1}$, a great improvement as compared to the LEP2 reach, where a senstitivity of order 2 for both couplings is found.
