Measurements of the inclusive Branching fractions of the Ds+ → η(η′) X decays
Abstract
Using e+ e- collision data collected with the BESIII detector at center-of-mass energies between $4.128$ and $4.226$ GeV, corresponding to an integrated luminosity of 7.33 fb−1, the inclusive branching fractions of the decays Ds+ → ηX and Ds+ → η′ X (X denotes any possible particles) are measured to be (30.72 ± 0.90 ± 0.46)% and (12.30 ± 0.94 ± 0.37)%, where the first uncertainties are statistical and the second systematic. The results are consistent with the previous CLEO measurements, with precision improved by factors of 2.8 and 1.9 for Ds+ → ηX and Ds+ → η′ X, respectively.
