摘要：

e analyze possible CP-violating effects induced in the Z decay with hard photon radiation by gamma Z Z and gammagammaZ anomalous vertices. We estimate the sensibility of future linear collider experiments on these couplings coming from CP-odd asymmetries associated to angular correlations of the three particle final state in e(+)e(-) --> Z --> mu(+)mu(-)gamma. We find that a linear collider with an integrated luminosity of 500 fb(-1) and roots- = 0.05 TeV can place the bound \h(1)(gamma,Z) \ < 0.92 at the 90% confidence level for these couplings.
