Description
The internal structure of nucleons remains a central challenge in hadronic physics, particularly in understanding how quarks and gluons contribute to their mass and spin. Introduced in the 1990s, the generalized parton distributions (GPDs) play a crucial role in providing multiple pieces of information to reveal these mysteries. Experimentally, GPDs can be accessed through the Compton Form Factors (CFFs), and the simplest process to probe them is Deeply Virtual Compton Scattering (DVCS).
The latest experiment in the Hall A/C GPD programs at Jefferson Lab (JLab) was performed from 2023 to 2024 using the newly installed Neutral Particle Spectrometer (NPS) in Hall C. The NPS calorimeter, constructed using 1080 lead tungstate (PbWO$_4$) crystals, offers high energy resolution for detecting photons emitted in DVCS processes, thereby playing a key role in measuring DVCS cross sections. In this talk, I will present our experimental setup and the status of data analysis.
