Abstract
Fermilab high-energy photoproduction experiment E687 provides a high statistics sample of the decay mode D+ → anti(K∗0) mu+nu (charge conjugates are implied). Our analysis yields a branching ratio of Gamma (D+ → anti(K∗0)mu+ν)/Gamma(D+ → K−pi+pi+) = 0.56±0.04±0.06. The ratios of the form factors governing the decay are measured to be Rν = 1.74 ±0.27±0.28 and R2 = 0.78±0.18±0.10, implying a polarization of Gammal/Gammat = 1.20±0.13 ±0.13 for the electron decay. Finally, we report new limits on the decay modes D+ → K-pi+mu+nu (nonresonent) and D+ → anti(K∗0) pi0 mu+nu.
