New Measurements of the D+ to K* mu nu Form Factor Ratios
Abstract
Using a large sample of D+ to K- pi+ mu+ nu decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: rv and r2. We find rv = 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 a previous paper.
