Measurements of the center-of-mass energies at BESIII via the di-muon process
(2016)From 2011 to 2014, the BESIII experiment collected about 5 fb$^{-1}$ data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing the di-muon process ... -
Observation of hc radiative decay hc › ??' and evidence for hc › ??
(2016)A search for radiative decays of the P-wave spin singlet charmonium resonance hc is performed based on 4.48 × 108 ? events collected with the BESIII detector operating at the BEPCII storage ring. Events of the reaction ... -

Measurement of the absolute branching fraction of D+ › K¯ 0e +?e via K¯ 0 › ? 0? 0 *
(IOPscience, 2016)By analyzing 2.93 fb-1 data collected at the center-of-mass energy ? s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D + › K¯ 0 e +?e to be B(D+ › K¯ 0 e +?e) = ... -

(2014)Using 1.06×108 ?(3686) events recorded in e+e- collisions at s?=3.686??GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/?›?? and ?? decays via ?(3686)›J/??+?-. No significant ... -
Observation of e +e - › ? 0? 0hc and a neutral charmoniumlike structure Zc(4020)0
(2014)Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of s?=4.23, 4.26, and 4.36 GeV, we observe e+e-›?0?0hc for the first time. The Born cross sections ...
