Abstract

We present a study of the Cabibbo-allowed semimuonic decay modes of the D_S⁺ produced in 600 GeV c π^- -emulsion interactions. From a signal of 18.7±4.9_-0.7^+0.4 events in the D_S⁺ → øμ⁺υ channel, the product of production cross section and partial width is measured with respect to that for D⁺ → K^*0 μ⁺υ to be ( σ(D_S⁺) σ(D⁺)). (Λ(D_S⁺ → øμ⁺ν)Λ(D⁺ → K^*0 μ⁺ν)) = 0.56 ± 0.14 ± 0.12. The form factor ratios in the decay, obtained by fitting to the decay angles and q², are A₂ (0)₁(0) = 2.1_-0.5^+0.6 ± 0.2 and V (0) A₁ (0) = 2.3_-0.9^+1.1 ± 0.4, where A₁ (0) and A₂ (0) are the axial vector form factors and V(0) is the vector form factor, evaluated at q² = 0. The first observation of D_S⁺ → (ημ⁺υ + η'μ⁺υ) is also reported, and Γ (D_S⁺ → (ημ⁺υ + η'μ⁺υ)) Γ (D_S⁺ → øμ⁺υ) is determined to be 3.9 ± 1.6.
