Abstract
Although the charmonium spectrum seems to be well investigated, charmonia can still be used as benchmarks to test QCD predictions, as these states lie in the transition region between perturbative and non-perturbative QCD. Despite the need for experimental confirmations, slowdowns arise from limited statistics of the production of non-vector states. Indeed, some charmonium states’ masses, widths and brancing fractions are still far from being precisely known. Since 2009, BESIII has been scanning and investigating the energy range between 2.0 and 4.9 GeV. Thanks to its largest data sets of charmonium resonances (J/ψ, ψ(2S), and ψ(3770)) in the world as well as other data sets at the centre-of-mass energies above 3.8 GeV, BESIII can overcome statistical limitations to shed light on open questions.
