Search for the reaction e(+) e(-) -> chi(cJ)pi(+)pi(-) and a Charmoniumlike Structure Decaying to chi(cJ)pi(+/-) between 4.18 and 4.60 GeV
(Amer Physical Soc., 2021)
We search for the process e(+)e(-) -> chi(cJ)pi(+) pi(-) (J = 0, 1, 2) and for a charged charmoniumlike state in the chi(cJ)pi +/- subsystem. The search uses datasets collected with the BESIII detector at the BEPCII storage ...
Measurement of the Branching Fraction for psi (3686) ->omega(KSKS0Y)-K-0
(Amer Physical Soc., 2021)
Analyzing (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector at the BEPCII collider, the psi(3686) -> omega(KSKS0)-K-0 decay is observed for the first time. The branching fraction for this decay ...
Measurement of the Absolute Branching Fraction of Lambda(+)(C) -> Pk(S)(0)Eta Decays
(Elsevier, 2021)
Based on 586 pb(-1) of e(+) e(-) annihilation data collected at a center-of-mass energy of root s = 4.6 GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Lambda(+)(c) -> pK(S)(0)eta ...
Amplitude Analysis and Branching-fraction Measurement of D-s(+) -> (KSK-)-K-0 pi(+)pi(+)

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 ...
Measurements of e(+) e(-) -> eta(c)pi(+)pi(-)pi(0), eta(c)pi(+)pi(-), and eta(c)pi(0)gamma at root s from 4.18 to 4.60 GeV, and search for a Z(c) state close to the D(D)over-bar threshold decaying to eta(c)pi at root s=4.23 GeV
(Amer Physical Soc., 2021)
We study eta(c) production at center-of-mass energies root s from 4.18 to 4.60 GeV in e(+)e(-) annihilation data collected with the BESIII detector operating at the BEPCII storage ring, corresponding to 7.3 fb(-1) of ...

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 ...
Measurement of Cross Section for e(+)e(-) -> Xi(0)(Xi)over-bar(0) Near Threshol

Using e(+)e(-) collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector at BEPCII and corresponding to an integrated luminosity of about 500 pb(-1), we measure the cross ...
Search for the Charged Lepton Flavor Violating Decay J/psi -> e tau

(Amer Physical Soc., 2021)
We report a measurement of the observed cross sections of e(+)e(-) -> J/psi X based on 3.21 fb(-1) of data accumulated at energies from 3.645 to 3.891 GeV with the BESIII detector operated at the BEPCII collider. In analysis ...
Oscillating Features in The Electromagnetic Structure of The Neutron
(Nature Research, 2021)
The complicated structure of the neutron cannot be calculated using first-principles calculations due to the large colour charge of quarks and the self-interaction of gluons. Its simplest structure observables are the ...
