Abstract

Using a large sample of charm semileptonic decays collected by the FOCUS photoproduction experiment at Fennilab, we present new measurements of two semileptonic branching ratios. We obtain values of Γ(D+ → K*0μ+ν)/Γ(D+ → K-π+π+) = 0.602 ± 0.010(stat) ± 0.021(sys) and Γ(Ds+ → φμ+ν)/Γ(Ds+ → φπ+) = 0.544 ± 0.033(stat) ± 0.048(sys). Our D+ → K*0μ+ν result includes the effects of the s-wave interference discussed in Phys. Lett. B 535 (2002) 43. © 2002 Elsevier Science B.V. All rights reserved.
