Abstract
Studies of the decay D0 + K-mu+ nu, are reported by Fermilab photoproduction experiment E687. The ratio BR( D0 -> K-mu+ nu(mu),)/BR( D0 -> K-pi+) is determined to be 0,852 +- 0.034 (statistical) +- 0.028 (systematic). Using this result and an isospin argument we infer the ratio BR(D0 -> K*-,mu+ nu(mu))/BR(D0->K- mu+ nu(mu)) = 0.62+- 0.07+- 0.09. The pole mass from the single pole form factor is measured to be M(pole) = l.87(-0.08-0.06)(+0.11+0.07) GeV/c2. Using M(pole) and BR( D0-> K-,mu+ nu(mu))/BR(D0->K-pi+), we calculate |f+(O)| = 0.71 +-0.03+-0.03. We also measure the ratio f-(0)/f+(O) = - 1.3(-3.4)(+3.6) +- 0.6
