Study of Nuclear TMDs in SIDIS with CLAS12 at Jefferson Lab
ORAL
Abstract
Transverse momentum dependent parton distributions (TMDs) describe how quarks and gluons move not only along the nucleon’s direction of motion but also in the transverse direction, revealing its three-dimensional momentum structure. While TMDs have been extensively studied in nucleons, we extend this framework to nuclear targets using Semi-Inclusive Deep Inelastic
Scattering (SIDIS) with the CLAS12 detector at Jefferson Lab(Fall 2023). A 10.5 GeV polarized electron beam was used on liquid deuterium (LD2) and solid C, Cu, and Sn targets to study nuclear effects on parton dynamics. We present a preliminary analysis focusing on multiplicity ratios, transverse momentum broadening, and unpolarized azimuthal moments (cos ϕ, cos 2ϕ), which probe nuclear modifications to parton propagation and transverse momentum distributions.
