Abstract
Selected results of BESIII are reported, including the observation of charged, charmonium-like states, the Zc(3900), Zc(4020), and Zc(4025); observation of e+e- → γX(3872); study of ηη system in J/ψ → γηη; baryon excited study in [Formula: see text]; precise measurements of the decay constant fD from D+ → μ+ν and form-factors in D0 → K-e+ν,π-e+ν.
Highlights
The BESIII1 experiment at the BEPCII collider has accumulated the world’s largest datasets at J/ψ, ψ(3686), and ψ(3770) energy region
Subsequent studies indicate that the Y (4260) state is not a conventional state of charmonium
Using 525 pb−1 data sample collected with the BESIII detector at a center-ofmass energy of 4.260 GeV, the process e+e− → π+π−J/ψ was studied
Summary
Selected results of BESIII are reported, including the observation of charged, charmonium-like states, the Zc(3900), Zc(4020), and Zc(4025); observation of e+e− → γX(3872); study of ηη system in J/ψ → γηη; baryon excited study in ψ(3686) → ppπ[0]; precise measurements of the decay constant fD from D+ → μ+ν and form-factors in D0 → K−e+ν, π−e+ν.
