Abstract:
Using a large sample of \phimndk{} decays
collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic form factor ratios: \rvee{} and \rtwo{}. We find rV= 1.549 \pm 0.250 \pm 0.148} and r2= 0.713 \pm 0.202 \pm 0.284. These values are consistent with \rvee{} and \rtwo{} form factors measured for the process \krzlndk{}.
