Abstract:
Hadronization, the non-perturbative QCD process by which colored quarks become color-neutral hadrons, remains a fundamental challenge to understand from first principles. To address this, a wide range of experiments - including Drell-Yan at Fermilab, heavy-ion collisions at RHIC and the LHC, semi-inclusive deep-inelastic scattering at DESY and Jefferson Lab, and e+e− studies at BEPC - have been conducted to provide complementary insights into short-distance QCD dynamics.
In this seminar, I will present results from SIDIS off nuclear targets, a program initiated by HERMES at DESY in 1990’s and now advanced with high-precision measurements with CLAS and CLAS12 at Jefferson Lab. Employing SIDIS’s ability to probe the time-dependence of hadronization by using nuclei of varying sizes, a series of measurements have been conducted employing a 5.014 GeV electron beam on a double-target system (D plus C, Fe or Pb) in CLAS and recently extended with 11 GeV upgrade using CLAS12. These studies explore hadron formation and attenuation, di-hadron dynamics, and Bose-Einstein correlations, while also offering potential insights into quark energy loss in cold nuclear matter and the search for diquark states. I will review recent CLAS results and discuss future opportunities at the Electron-Ion Collider and potential 22 GeV upgrade at Jefferson Lab.
