Measurements of Charm Fragmentation into Dₛ*⁺ and Dₛ+ in e+e- Annihilations at √s=10.5 GeV

الأصل · EN

A study of charm fragmentation into Dₛ*⁺ and Dₛ+ in e+e- annihilations at √s=10.5 GeV is presented. This study using 4.72 ± 0.05 fb⁻¹ of CLEO II data reports measurements of the cross-sections σ(Dₛ*⁺) and σ(Dₛ+) in momentum regions above x=0.44, where x is the Dₛ momentum divided by the maximum kinematically allowed Dₛ momentum. The Dₛ vector to vector plus pseudoscalar production ratio is measured to be Pᵥ(x(Dₛ+)>0.44)=0.44±0.04
