Description
We have studied the exclusive semileptonic decay mode D+→ bar K0e+νe in the Fermilab photoproduction experiment E691. We find the ratio of B(D+→ bar K0e+νe)/B(D+→K-π+π+) to be 0.66±0.09±0.14, corresponding to a D+→ bar K0e+νe branching ratio of 6.1±0.9±1.6%. Combining this result with our measurement of the D+ lifetime, we find Γ(D+→ bar K0e+νe)=(5.6±0.8±1.5)x1010 s-1. We also find, using E691 averages, the ratio of decay rates Γ(D→K*eν)/Γ(D→Keν) to be 0.55±0.14
