Theoretical expectations for T-violation in the nucleon-nucleon interaction

The possible size of T-violating effects in the N-N interaction are considered both with and without P-violation. For T-violation it is found that in several gauge models P,T-violating effects in the N-N interaction could be large enough to be observable in some current and contemplated experiments. Concerning P-conserving T-violating effects it is noted that in gauge models with elementary quarks the flavor-conserving nonleptonic interactions of the quarks do not contain in first order a P-conserving T-violating component
