Abstract

Fermilab high-energy photoproduction experiment E687 measures a branching ratio of Γ (DS+ → φμ+ν) /Γ (DS+ → φμ+) = 0.58 ± 0.17 (stat) ± 0.07 (sys). This branching ratio is combined with theoretical inputs to obtain a new measurement of the DS+ absolute branching ratio of Γ (DS+ → φμ+) / Γ (DS+ → all) = 0.031 ± 0.009 (stat 0.005 (sys) ± 0.004 (theoretical).
