Amplitude analysis and branching-fraction measurement of Ds+ → π + π 0 η′
(Springer Science and Business Media Deutschland GmbH, 2022)
Using data collected with the BESIII detector in e+e− collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb−1 of integrated luminosity, we report the amplitude analysis and ...
Observation of ψ (3686) →n n ̄ and improved measurement of ψ (3686) →p p ̄
(Amer Physic Soc., 2019)
We observe the process psi(3686) -> p (p) over bar eta' for the first time, with a statistical significance higher than 10 sigma, and measure the branching fraction of J/psi -> p (p) over bar eta' with an improved accuracy ...
Observation of J/Psi Electromagnetic Dalitz Decays to X(1835), X(2120), and X(2370)
(American Physical Society, 2022)
Using a sample of about 1010 J/ψ events collected at a center-of-mass energy s=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e+e-π+π-η′, with η′→γπ+π- and η′→π+π-η, have been studied. The decay ...
Observation of a State X(2600) in the pi(+) pi(-)eta' System in the Process J/psi -> gamma pi(+)pi(-)eta'
(American Physical Society, 2022)
Based on (10087±44)×106 J/ψ events collected with the BESIII detector, the process J/ψ→γπ+π-η′ is studied using two largest decay channels of the η′ meson, η′→γπ+π- and η′→ηπ+π-, η→γγ. A new resonance, which we denote as ...
Search for D0 ??? and improved measurement of the branching fraction for D0 ??0?0
