Observation of a charged charmoniumlike structure in e+ e- → (D* D*)± π∓ at √s = 4.26  GeV.
We study the process e+ e- →(D* D*)± π∓ at a center-of-mass energy of 4.26 GeV using a 827  pb(-1) data sample obtained with the BESIII detector at the Beijing Electron Positron Collider. Based on a
Observation of a charged charmoniumlike structure Zc(4020) and search for the Zc(3900) in e+e-→π+π-hc.
TLDR
E+e-→π+π-hc at center-of-mass energies from 3.90 to 4.42 GeV is studied by using data samples collected with the BESIII detector operating at the Beijing Electron Positron Collider and a distinct structure, referred to as Zc(4020), is observed in the π±hc mass spectrum.
Observation of a charged (DD*)± mass peak in e+ e- → πDD* at sqrt[s] = 4.26  GeV.
TLDR
The mass and width of the structure, which is referred to as Zc(3885), are 2σ and 1σ, respectively, below those of the Zc (3900) → π± J/ψ peak observed by BESIII and Belle in π+ π- J/ π final states produced at the same center-of-mass energy.
Confirmation of the X(1835) and observation of the resonances X(2120) and X(2370) in J/ψ→γπ+π-η'.
TLDR
The X(1835), which was previously observed by BESII, is confirmed with a statistical significance that is larger than 20σ, and the angular distribution of the radiative photon is consistent with expectations for a pseudoscalar.
