Production of two non-conjugate leptoquarks in e−e− collisions

We study the production of scalar and vector leptoquarks in e−e− scattering. We use the most general couplings to the known fermions which are dimensionless, baryon and lepton number conserving, and SU(3)c ⊗ SU(2)L ⊗ U(1)Y invariant. Expressions are presented for production cross sections and predictions are given for future linear colliders.
