Abstract:
Using a large sample of $D^+ \rightarrow K^- \pi^+ \mu^+ \nu$ 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 rV= 1.504 \pm 0.057 \pm 0.039 and r2 = 0.875 \pm 0.049 \pm 0.064. Our form factor results include the effects of the $s$-wave interference discussed in Reference~\cite{anomaly}.
