Is T good in strong interactions

A model for C- and T-violation in the strong interaction due to A1 exchange is reviewed in the light of recently published polarization minus asymmetry (P - A) data. The model is seen to predict P - A too large by a factor of three or four at 500 and 600 MeV. However, it is argued that the models' direct and derivative coupling constants for the A1, which are responsible for the C-violation, are probably three times too large, based on reasonable values for the rho-nucleon coupling constant. Readjusting the A1 coupling constants then restores agreement with all medium energy nucleon-nucleon tests. (Auth.)
