Perspectives On Observing Cp Violation From Beyond The Standard Model At Hera

"The possibility of observing CP (or T) violation from the leptonic sector of the Standard Model in $e sp pm p$ scattering at HERA is investigated. Neglecting fermion masses, an effective-Lagrangian approach is used to compute model-independent predictions of an eventual CP-breaking asymmetry. The asymmetry is defined as the difference between the number of final electrons (for charged-current events), or jets (for neutral-current events), that leave the detector to the left and right of the plane defined by the axis of the incoming electron beam and its direction of polarization. It is found that HERA should be reasonably sensitive to CP-violation in the case of charged-current $e sp- p$ scattering events." --
