CP-violating anomalous WWγ couplings in e+e- collisions

We investigate the sensitivity of future linear collider experiments to CP violating WWγ couplings in the process e⁺e^--->νν¯γ. 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 κ~_γ<0.18, λ~_γ<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 sensitivity of order 2 for both couplings is found. © 1999
