Abstract
We present a new measurement of the branching ratio of the Cabibbo suppressed decay D-0 --> pi(-) mu(+) nu relative to the Cabibbo favored decay D-0 --> K- mu(+) nu and an improved measurement of the ratio \f(+)(pi)(0)/f(+)(K)(0)\ Our results are 0.074 +/- 0.008 +/- 0.007 for the branching ratio and 0.85 +/- 0.04 +/- 0.04 +/- 0.01 for the form factor ratio, respectively.
