Observation of hc radiative decay hc › ??' and evidence for hc › ??
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 ...
Observation of pseudoscalar and tensor resonances in J/?›???
Based on a sample of (1310.6±10.5)×106 J/? events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/?›??? is performed in order to study the intermediate states. ...
Measurement of the e+e- › ?+?- cross section between 600 and 900 MeV using initial state radiation
We extract the e+e-›?+?- cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb-1 taken at a center-of-mass energy ...

Measurement of the branching fraction for ?(3770) › ??c0
By analyzing a data set of 2.92fb-1 of e+e- collision data taken at s=3.773GeV and 106.41×106 ?(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the ...
Measurement of azimuthal asymmetries in inclusive charged dipion production in e + e - annihilations at ? s = 3.65 GeV
(APS Physics, 2016)
We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e(+) e(-) -> pi pi X based on a data set of 62 pb(-1) at the center-of-mass energy of 3.65 GeV collected with the SESIII ...
Search for a light CP-odd Higgs boson in radiative decays of J/psi
We search for a light Higgs boson A0 in the fully reconstructed decay chain of J/?›?A0, A0›µ+µ- using (225.0±2.8)×106 J/? events collected by the BESIII experiment. The A0 is a hypothetical CP-odd light Higgs boson predicted ...
