Calculation of the induced pseudotensor term in Λ beta decay

Mesonic second-class currents have been studied in semileptonic 6, 8=0 transitions. The closed-loop diagram is finite for the 7rcu current, and its energy-dependent lepton part is dominant over the contributions from the two-body exchange diagram. The two-body exchange diagram has energy-dependent and energy-independent lepton parts, which are of comparable magnitude for the A=12 triplet. A general form of the mesonic current has also been considered. A general theory of second-class effects, including both mesonic currents and the induced-tensor term for f t values and X/P+ ratios, has been discussed.
