Description:
Using a data sample of 448×106 ψ(3686) events collected with the BESIII detector operating at the BEPCII storage ring, the decays ψ(3686)→γη and ψ(3686)→γπ0 are observed with a statistical significan

Description:
We present first evidence for the process e+e−→γηc(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 c

Description:
The cross section for the process e+e−→π+π−J/ψ is measured precisely at center-of-mass energies from 3.77 to 4.60 GeV using 9 fb−1 of data collected with the BESIII detector operating at the BEPCII s

Description:
We observe for the first time the process e+e−→ηhc with data collected by the BESIII experiment. Significant signals are observed at the center-of-mass energy s=4.226 GeV, and the Born cross section i

Description:
The cross sections of e+e−→π+π−hc at center-of-mass energies from 3.896 to 4.600 GeV are measured using data samples collected with the BESIII detector operating at the Beijing Electron Positron Colli
