Description
For more than 50 years, bound hadrons have been known to undergo non-trivial modifications due to the presence of the cold nuclear medium."During this time, experimental measurements at collider facilities have focused on how the one-dimensional structure of hadrons is modified, with global QCD analyses proving extremely successful in extracting these distributions. More recently, we have used experimental data from Jefferson Lab to constrain the nuclear-modified fragmentation functions. Our methodology incorporates the global set of experimental data from both Drell-Yan production and Semi-Inclusive Deep Inelastic Scattering. Through a comprehensive global extraction of these distributions, we demonstrate the effectiveness of this extension by strongly describing the entire global dataset. A focal point of this paper is the impact of recent Jefferson Lab measurements. Most notably, to simultaneously describe experimental data at Jefferson Lab and HERMES we find that it is necessary to introduce a parameter which accounts for the non-perturbative scale evolution of the nTMDs. Additionally, we assess the kinematic coverage of the experimental data and provide insights into experimental opportunities at Jefferson Lab, future Electron-Ion Colliders, RHIC, and the LHC. These opportunities have the potential to significantly enhance and refine global analyses of nuclear-modified TMDs, contributing to a deeper understanding of the structure of cold nuclear matter.
