Search for intermediate resonances and dark gauge bosons in J/psi -> gamma pi(0)eta '
(Amer Physical Soc., 2020)
We report on an analysis of the decay J/psi -> gamma pi(0)eta' using a sample of o1310.6 +/- 7.0THORN x 10(6) J/psi events collected with the BESIII detector. We search for the CP-violating process eta c -> pi(0)eta' and ...

(Elsevier, 2020)
We report a study of the e(+)e(-) -> D+D-pi(+)pi(-) process using e(+)e(-) collision data samples with an integrated luminosity of 2.5 fb(-1) at center-of-mass energies from 4.36 to 4.60 GeV, collected with the BESIII ...
Measurement of Cross Section for e(+)e(-) -> Xi(0)(Xi)over-bar(0) Near Threshol
(Elsevier, 2021)
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)
A search for the charged lepton flavor violating decay J/psi -> e(+/-)tau(-/+) with tau(-/+) -> pi(-/+)pi(0)nu(tau) is performed with about 10 x 10(9) J/psi events collected with the BESIII detector at the BEPCII. No ...
