Measurement of the Branching Fractions D_s⁺ → η′Χ and D_s^+ → η′ρ⁺ in e⁺e⁻ → D_s^+D_s^-
(Elsevier B.V., 2015-11-27)
We study D_s⁺ decays to final states involving the η' with a 482 pb⁻¹ data sample collected at √s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions ℬ(D_s⁺ → η'Χ) = (8.8 ± 1.8 ...
