Observation of the Doubly Cabibbo-Suppressed Decay D+ -> K+ pi(+) pi(-) pi(0) and Evidence for D+ -> K+ omega
(Amer Physical Soc., 2020)
Using 2.93 fb(-1) of e(+)e(-) collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, the first observation of the doubly Cabibbo-suppressed decay D+-> K+pi(+)pi(-)pi(0) is reported. After ...
Model-Independent Determination of the Spin of the Omega(-) and Its Polarization Alignment in psi(3686) -> Omega(-)(Omega)over-bar(+)
(Amer Physical Soc., 2021)
We present an analysis of the process psi(3686) -> Omega(-)(Omega) over bar (+)(Omega(-). K-Lambda, (Omega) over bar (+) K+ (Lambda) over bar,(Omega) over bar (+) Lambda -> p pi(-), (Lambda) over bar -> p (p) over bar ...
Study of psi(3686) -> Lambda(Lambda)over-bar omega
(AMER PHYSICAL SOC, 2022)
Based on a data sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider, the branching fraction of psi(3686) -> Lambda(Lambda) over bar omega is measured to be (3.30 +/- ...
Amplitude analysis and branching fraction measurement of the decay Ds+ → K+ π + π − π 0
(Springer Science and Business Media Deutschland GmbH, 2022)
The singly Cabibbo-suppressed decay Ds+ → K+π+π−π0 is observed by using a data set corresponding to an integrated luminosity of 6.32 fb−1 recorded by the BESIII detector at the centre-of-mass energies between 4.178 and ...
Amplitude analysis and branching fraction measurement of the decay D+ → KS0 π+ π0 π0
(Springer Science and Business Media Deutschland GmbH, 2023)
Using 2.93 fb−1 of e+ e− collision data collected with the BESIII detector at the center-of-mass energy 3.773 GeV, we perform the first amplitude analysis of the decay D+ → KS0 π+ π0 π0 and determine the relative magnitudes ...

Searching for beauty-fully bound tetraquarks using lattice nonrelativistic QCD
(American Physical Society, 2018)
Using a data sample of (448.1±2.9)×106 ?(3686) events collected with the BESIII detector at the BEPCII collider, we present measurements of branching fractions for the decays ?cJ??+?- and ?0?0. The decays ?c1,2??+?- and ...
Measurement of cross sections for e(+) e(-) -> mu(+) mu(-) at center-of-mass energies from 3.80 to 4.60 GeV
(Amer Physical Soc., 2020)
The observed cross sections for e(+)e(-) -> mu(+) mu(-) at energies from 3.8 to 4.6 GeVare measured using data samples taken with the BESIII detector operated at the BEPCII collider. We measure the muonic widths and determine ...
Study of BESIII Trigger Efficiencies with the 2018 J/psi Data
(2021)
Using a dedicated data sample taken in 2018 on the J/psi peak, we perform a detailed study of the trigger efficiencies of the BESIII detector. The efficiencies are determined from three representative physics processes, ...
