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: r v and r 2 . We find r v =1.504±0.057±0.039 and r 2 =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.
