We have compared our results with previous CP violation experiments in this and other decay modes of the neutral kaon. We find consistency among the experiments and consistency with the predictions of the superweak theory.
We have studied the decay[bar B][yields] D[ell][bar[nu]], where[ell]= e or[mu]. From a fit to the differential decay rate d[Lambda]/dw we measure the rate normalization F[sub D](1)V[sub cb] and form factor slope[rho][sub D][sup 2], and, using measured values of[tau][sub B], find[Lambda]([bar B][yields] D[ell][bar[nu]])= (12.0[+-] 0.9[+-] 2.1) ns[sup -1]. The resulting branching fractions are[Beta]([bar B][sup 0][yields] D[sup+][ell][sup -][bar[nu]])= (1.87[+-] 0.15[+-] 0.32)% and[Beta](B[sup -][yields] D[sup 0][ell][sup -][bar[nu]])= (1.94[+-] 0.15[+-] 0.34)%. The form factor parameters are in agreement with those measured in[bar B][yields] D*[ell][bar[nu]] decays, as predicted by heavy quark effective theory.
