J. Engel et al., EFFECTIVE LAGRANGIANS AND PARITY-CONSERVING TIME-REVERSAL VIOLATION AT LOW ENERGIES, Physical review. D. Particles and fields, 53(9), 1996, pp. 5112-5114
Using effective Lagrangians, we argue that any time-reversal-violating
but parity-conserving effects are too small to be observed in flavor-
conserving nuclear processes without dramatic improvement in experimen
tal accuracy. In the process we discuss other arguments that have appe
ared in the literature.
