Measurement of the absolute branching fraction of D+ → K¯ 0e +νe via K¯ 0 → π 0π 0 *
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 +νe to be B(D+ → K¯ 0 e +νe) = ...

Observation of e +e − → π 0π 0hc and a neutral charmoniumlike structure Zc(4020)0
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−→π0π0hc for the first time. The Born cross sections ...
Study of ψ decays to the Ξ−Ξ¯+ and Σ(1385)∓Σ¯(1385)± final states
We study the decays of the charmonium resonances J/ψ and ψ(3686) to the final states Ξ−Ξ¯+, Σ(1385)∓Σ¯(1385)± based on a single baryon tag method using data samples of (223.7±1.4)×106 J/ψ and (106.4±0.9)×106 ψ(3686) events ...
Observation of pseudoscalar and tensor resonances in J/ψ→γφφ
Based on a sample of (1310.6±10.5)×106 J/ψ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→γϕϕ is performed in order to study the intermediate states. ...
Observation of e+e−→ωχc1,2e+e−→ωχc1,2 near s√s = 4.42 and 4.6 GeV
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−→ωχc1,2e+e−→ωχc1,2 are observed for the first time. With ...
Observation of the Singly Cabibbo-Suppressed Decay D + → ω π + and Evidence for D 0 → ω π 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 + → ωπ+ and D 0 → ωπ0 . A double tag technique is ...
Observation of hc radiative decay hc → γη′ and evidence for hc → γη
A search for radiative decays of the P-wave spin singlet charmonium resonance hc is performed based on 4.48 × 108 ψ events collected with the BESIII detector operating at the BEPCII storage ring. Events of the reaction ...
Study of J/Psi -> p(p)over-bar phi at BESIII
Using a data sample of 1.31×109 J/ψ events accumulated with the BESIII detector, the decay J/ψ→pp¯ϕ is studied via two decay modes, ϕ→KS0KL0 and ϕ→K+K-. The branching fraction of J/ψ→pp¯ϕ is measured to be B(J/ψ→pp¯ϕ)=[5 ...
