Abstract
Fermilab high-energy photoproduction experiment E687 provides a high statistics sample of the decay mode D+ → K*0μ+ν (charge conjugates are implied). Our analysis yields a branching ratio of Γ (D+ → K*0μ+ν) Γ (D+ → K-π+π+) = 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 Γl Γt = 1.20±0.13 ±0.13 for the electron decay. Finally, we report new limits on the decay modes D+ → K-π+μ+ν (nonresonent) and D+ → K*0π0μ+ν.
