New measurements of the D+→(K)over-bar*0μ+ν form factor ratios

Using a large sample of D+ --> K- pi(+) mu(+) nu decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: r(nu) and r(2). We find r(nu) = 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.
