PROBING CP VIOLATION IN GAMMA-GAMMA-]W- WITH POLARIZED PHOTON BEAMS(W)

We demonstrate in a general framework that polarized photons by backsc attered laser beams of adjustable frequencies at a TeV linear e(+)e(-) collider provide us with a very efficient mechanism to probe CP viola tion in two-photon collisions. CP violation in the process gamma gamma --> W+W- is investigated in detail with linearly polarized photon bea ms. There are two useful CP-odd asymmetries that do not require detail ed information on W decay products. The sensitivity to the CP-odd form factors are studied quantitatively by assuming a perfect e-gamma conv ersion and the 20 fb(-1) e(+)e(-) integrated luminosity at the e(+)e(- ) c.m. energies root s = 0.5 and 1.0 TeV. The sensitivity is so high t hat such experiments will allow us to probe new CP violation effects b eyond the limits from some specific models with reasonable physics ass umptions. We find that a counting experiment of W+W- events in the two -photon mode with adjustable laser frequencies can have much stronger sensitivity to the CP-odd gamma(gamma)WW form factors than can a W+W- decay-correlation experiment with a perfect detector achieve in the e( +)e(-) mode.
