Amplitude Analysis and Branching-fraction Measurement of D-s(+) -> (KSK-)-K-0 pi(+)pi(+)
(Amer Physical Soc., 2021)
Using 6.32 fb(-1) of e(+)e(-) collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the D-s(+) -> (KSK-)-K-0 pi(+)pi(+) decays is performed for ...
Search for the X (2370) and observation of eta(c) -> eta eta eta ' in J/psi -> gamma eta eta eta '
(Amer Physical Soc., 2021)
Using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, we perform a study of J/psi -> gamma eta eta eta' to search for the X(2370) and eta(c) in the eta eta eta' invariant mass distribution. No ...
Observation of a Near-Threshold Enhancement in the Lambda(Lambda)over-bar mass spectrum from e(+)e(-) -> phi Lambda(Lambda)over-bar at root S is from 3.51 to 4.60 GeV
(Amer Physical Soc., 2021)
The process e(+)e(-) -> phi Lambda(Lambda) over bar is studied using data samples collected with the BESIII detector at the BEPCII Collider at center of mass energies root S ranging from 3.51 GeV to 4.60 GeV. An enhancement ...

(Amer Physical Soc., 2019)
Utilizing the dataset corresponding to an integrated luminosity of 2.93 fb(-1) at root s = 3.773 GeV collected by the BESIII detector, we report the first amplitude analysis and branching fraction measurement of the D-0 ...
Precision measurements of the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+) Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV
(Amer Physic Soc., 2019-04-11)
Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+ )Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV, corresponding ...
Partial wave analysis of psi(3686) -> K+ K- eta
(Amer Physical Soc., 2020)
Using a sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector, we perform the first partial wave analysis of psi(3686) -> K+K- eta. In addition to the well established states, phi(1020), ...
Determination of the Spin and Parity of the Z(c)(3900)
(Amer Physic Soc., 2017)
The spin and parity of the Z(c)(3900)(+/-) state are determined to be J(P) = 1(+) with a statistical significance larger than 7 sigma over other quantum numbers in a partial wave analysis of the process e(+)e(-) -> pi(+)pi(-) ...

By analyzing an e+e- annihilation data sample corresponding to an integrated luminosity of 2.93 fb-1 collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fraction of the ...
Measurement of The Absolute Branching Fractions of J/ψ →γη and η Decay Mode
(American Physical Society, 2021)
Based on a data sample of (1.0087±0.0044)×1010 J/ψ events collected by the BESIII detector at the BEPCII accelerator, the absolute branching fraction (BF) of the decay J/ψ→γη is measured with high precision using events ...
