We study the possibility of a large CP/T-violation in lepton pair production in the collisions of polarized protons at RHIC-BNL. We propose the single transverse spin asymmetry which quantifies the possible CP/T-violating effect in this reaction and advocate it as a sensitive indicator of physics beyond the Standard Model (SM). We consider two examples of mechanisms beyond the SM which can generate the non-zero asymmetry of this type. They rely on the R-parity violating interactions of supersymmetric models and on the phenomenological tensor interactions. We estimate the prospects for observing this effect in a future experiment.
