15:00 → 15:25 Recent results on GPDs from CLAS12 at JLab

Abstract:

In nucleon structure studies, Generalized Parton Distributions (GPDs) are multidimensional structure functions that encode information about the mechanical and spin properties of the nucleon through the correlation between the longitudinal momentum and transverse position of its constituent partons. The golden channel for their study is the Deeply Virtual Compton Scattering (DVCS) reaction, which enables a two-dimensional mapping of GPDs through the measurement of spin-dependent observables. This talk will present recent results from the CLAS12 DVCS program at Jefferson Lab, with particular focus on recent Beam Spin Asymmetry measurements at small nucleon momentum transfer and their consequences for GPD models. In addition, we discuss prospective measurements from the forthcoming CLAS12 luminosity upgrade, which will enable a three-dimensional mapping of GPDs via the Double DVCS reaction.

15:25 → 15:40 Q&A and Discussion

15:40 → 16:05 Exclusive, Diffractive, and Tagged Physics at ePIC: Physics Opportunities and Detector Systems

Abstract:

Exclusive, diffractive, and tagged measurements are a central component of the ePIC physics program at the Electron-Ion Collider, providing unique access to the spatial and gluonic structure of nucleons and nuclei. This talk will review the physics opportunities available during the Early Science running period and their evolution toward the full EIC capabilities. The detector systems enabling this program will also be discussed, especially the Roman Pot system and far-forward instrumentation, where French contributions play a prominent role, together with the backward electromagnetic calorimeter, essential for DIS kinematics and electron reconstruction.
