Abstract: | For the case of longitudinally polarized primary beams, effects are investigated that are induced by four-fermion contact interactions in the process e+e? → e+e? occurring at linear electron-positron colliders of energy in the range \(\sqrt s = 0.5 - 1 TeV\). Model-independent constraints on the parameters of four-fermion contact interactions are obtained. It is shown that the sensitivity of the Bhabha process to the parameter ΛLR is considerably higher than the sensitivity of the leptonic process e+e? → μ+μ?; at the same time, the sensitivities of these processes to the parameters ΛRR and ΛLL are commensurate. |
