Özet

We investigate the constraints on CP-violating triple WW gamma gauge boson couplings through the process e gamma -> W nu(e). Considering the longitudinal and transverse polarization states of the final W and incoming polarized beams, we find 95% confidence level limits on CP odd anomalous coupling parameters (lambda) over tilde and (kappa) over tilde with an integrated luminosity of 500 fb(-1) and root s = 0.5, 1 and 1.5 TeV energies. It is shown that the initial and final state polarizations improve the sensitivity limits of (lambda) over tilde by a factor of 1.3-1.6 and of (kappa) over tilde by a factor of 5.2-9.
