Evidence for e(+)e(-) -> gamma eta(c)(1S) at center-of-mass energies between 4.01 and 4.60 GeV
(Amer Physical Soc., 2017)
We present first evidence for the process e(+)e(-) -> gamma eta(c)(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born cross ...
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 the Y(4230) and a new structure in e(+)e(-) -> K+ K- J/psi
(IOP Publishing Ltd, 2022)
The cross sections of e(+)e(-) -> K+K- J/psi at center-of-mass energies from 4.127 to 4.600 GeV are measured based on 15.6 fb(-1) data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant ...
First Measurement of Polarizations in the Decay D-0 -> omega phi
(Amer Physical Soc., 2022)
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at a center-of-mass energy root s = 3.773 GeV by the BESIII detector, the decay D-0 -> omega phi is observed for the first time. The ...

(Elsevier, 2021)
The Born cross sections of the e(+)e(-) -> Sigma(+)(Sigma) over bar (-) and e(+)e(-)-> Sigma(-)(Sigma) over bar (+) processes are determined for centerof-mass energy from 2.3864 to 3.0200 GeV with the BESIII detector. The ...
