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 ...
Search for a light CP-odd Higgs boson in radiative decays of J/psi
(2016)
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 ...

Improved measurement of the absolute branching fraction of D+ -> (K)over-bar(0)mu(+)nu(mu)
(Springer, 2016)
By analyzing 2.93 fb(-1) of data collected at root s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction B(D+ -> (K) over bar (0) (+)(mu)nu(mu)) = (8.72 +/- 0.07(stat). +/- 0.18(sys).) %, which ...
Measurement of Singly Cabibbo Suppressed Decays ?c+ ?p?+?- and ?c+ ?pK+K-
(American Physical Society, 2016)
Using 567 pb-1 of data collected with the BESIII detector at a center-of-mass energy of s=4.599 GeV, near the ?c+?c- threshold, we study the singly Cabibbo-suppressed decays ?c+?p?+?- and ?c+?pK+K-. By normalizing with ...
Observation of pseudoscalar and tensor resonances in J/psi -> gamma phi phi
(American Physical Society, 2016)
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. ...

Observation of e(+)e(-) -> omega chi(c1,2) near root s=4.42 and 4.6 GeV
(2016)
BEPC-BES. Based on data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s?>s> 4.4 GeV, the processes e+e-›??c1,2e+e-›??c1,2 are observed for the first time. With ...
Observation of the Singly Cabibbo-Suppressed Decay D + › ? ? + and Evidence for D 0 › ? ? 0
(APS Physics, 2016)
Based on 2.93 fb-1 e +e - collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays D + › ??+ and D 0 › ??0 . A double tag technique is ...
