Abstract:We investigate the consequences of a CP violating gauge invariant pointlike four-fermion interaction at the TeV scale. It induces an enhancement of the production cross-sections (sigma left( {pbar p to e^ - bar v_e + X} right)) and (sigma left( {pbar p to e^ + bar v_e + X} right)) , together with a CP violating relative difference between these cross-sections at the % level, due to interference with radiative corrections. A complete calculation of the CP asymmetry is made for different values of the center of mass energy (sqrt s = 2, 10, 40 TeV) , 40 TeV.
