| dc.description | Using data collected by the fixed target Fermilab experiment FOCUS, we present several first measurements for the semileptonic decay $D^0 \to \bar{K}^0π^-μ^+ν$. Using a model that includes a $\bar{K}^0 π^-$ S-wave component, we measure the form factor ratios to be r_v= 1.706+-0.677+-0.342 and r_2= 0.912+-0.370+-0.104 and the S-wave amplitude to be A=0.347+-0.222+-0.053 GeV^-1. Finally, we measure the vector semileptonic branching ratio $\frac{Γ(D^0 \to K^{*}(892){-}μ^+ν)}{Γ(D^0 \to \bar{K}^0π^-π^+)}= 0.337+-0.034+-0.013. | |
