International workshop on CLAS12 physics and future perspectives at JLab

21 mars 2023, 08:00 → 24 mars 2023, 14:10 Europe/Paris

Auditorium (CNRS headquarters)

Silvia NICCOLAI (IJCLab)

The International workshop on CLAS12 physics and future perspectives at JLab will focus on recent results of the ongoing experiments of CLAS12 as well as on the medium-to-long term perspectives for physics at Jefferson Lab. The workshop will bring together experimentalists and theoreticians, experts in perturbative QCD, phenomenology of electromagnetic processes, hadron structure, baryon and mesons spectroscopy, and nuclear effects, to discuss the impact of present and future CLAS12 experiments, assess the reach of present theoretical methods, identify directions for further developments.
