Abstract

Studies of the decay D0 → K-μ+νμ are reported by Fermilab photoproduction experiment E687. The ratio BR(D0 → K-μ+νμ) BR(D0 → 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(D0 → K*-μ+νμ) BR(D0 → K-μ+νμ) = 0.62 ± 0.07 ± 0.09. The pole mass from the single pole form factor is measured to be Mpole = 1.87-0.08-0.06+0.11+0.07 GeV/c2. Using Mpole and BR(D0 → K-μ+νμ) BR(D0 → 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.
