Description
Since 2009, the BESIII experiment jas been collecting $e^+e^-$ physics data in the energy range between 2.0 up to 4.9 GeV. This allowed the BESIII Collaboration to cllect the largest datasets of charmonium $J/\psi$, $\psi(2S)$ and $\psi(3770)$. In particular, the radiative decay of the $J/\psi$ provide a promising hunting ground for glueballs, of which the $X(2370)$ represets a promising candidate. Moreover, the studies of hadron production have lead to the obseravion of SU(3)–flavor breaking effects and rare decay modes of $\psi(3770)$ and $\psi(4160)$ resonances.
Looking at the future, the inner drift chamber has been replaced by a three‐layer cylindrical GEM inner tracker (CGEM‐IT), achieving ≲200 μm spatial resolution and ≥95 % layer efficiency, to secure high‐precision tracking. Morover, BESIII will triple its current luminoisity and in 2028 the beam energy will rise up to 5.6 GeV in order to explore the direct production of charmed baryons.
