Using a large sample of D+ → K-π+μ+ν decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: rν and r2.

Abstract

Using a large sample of D+ → K-π+μ+ν decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: rν and r2. We find rν = 1.504 ± 0.057 ± 0.039 and r2 = 0.875 ± 0.049 ± 0.064. Our form factor results include the effects of the s-wave interference discussed in Phys. Lett. B 535 (2002) 43.
