Speaker: Marco Scodeggio (Istituto Nazionale di Fisica Nucleare)

Since 2009, the BESIII experiment at the BEPCII lepton collider has played a central role in hadron spectroscopy, in measurements of charmed-hadron decay properties, and in precision QCD studies at the interface between the perturbative and non-perturbative regimes.

Recently, an extensive upgrade program has been completed: the accelerator luminosity in the high center of mass energy region has been increased by a factor of three, and the innermost tracking system has been replaced by the new CGEM-IT, an inner tracker based on cylindrical gas electron multiplier (GEM) technology, originally developed for the KLOE-2 experiment at LNF.

In this seminar, the current status of the BESIII experiment will be presented, highlighting some recent physics results and discussing the status of the CGEM-IT detector.
