Study of J/psi and psi(3686) -> Sigma(1385)(0)(Sigma)over-bar(1385)(0) and Xi(0)(Xi)over-bar(0)
(Elsevier Science, 2017)
We study the decays of J/psi and psi(3686) to the final states Sigma(1385)(0)(Sigma) over bar (1385)(0) and Xi(0)(Xi) over bar (0) based on a single baryon tag method using data samples of (1310.6 +/- 7.0) x 10(6) J/psi ...
Determination of the number of J/psi events with inclusive J/psi decays
(Chinese Physical, 2017)
A measurement of the number of J/psi events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/psi. The number of J/psi events taken in 2009 is recalculated to be (223.7 +/- ...
Measurement of branching fractions for psi(3686) -> gamma eta ', gamma eta, and gamma pi(0)
(Amer Physical Soc., 2017)
Using a data sample of 448 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII storage ring, the decays psi(3686) -> gamma eta and psi(3686) -> gamma pi(0) are observed with a statistical ...
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 ...
First Measurement of Polarizations in the Decay D-0 -> omega phi

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 ...
Measurements of Sigma(+) and Sigma(-) time-like electromagnetic form factors for center-of-mass energies from 2.3864 to 3.0200 GeV
