Frabetti, P. L.

Studies of the decay D 0 → K - μ + ν μ are reported by Fermilab photoproduction experiment E687. The ratio BR(D 0 → K - μ + ν μ ) BR(D 0 → K - π + ) is determined to be 0.852 ± 0.034 (statistical) ± 0.028 (systematic). Using this result and an isospin argument we infer the ratio BR(D 0 → K *- μ + ν μ ) BR(D 0 → K - μ + ν μ ) = 0.62 ± 0.07 ± 0.09 . The pole mass from the single pole form factor is measured to be M pole = 1.87 0.08-0.06 +0.11+0.07 GeV/ c 2 . Using M pole and BR(D 0 → K - μ + ν μ ) BR(D 0 → K - π + ) , we calculate | f + (0)| = 0.71 ± 0.03 ± 0.03. We also measure the ratio f - (0) f + (0) = -1.3 -3.4 +3.6 ± 0.6 .
