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.
About the speaker:
Taisiya Mineeva is a Senior Researcher at the Universidad de La Serena, Chile and an associate researcher in Centro Científico Tecnológico de Valparaíso (CCTVaL), Chile. With a Ph.D. in Physics from the University of Connecticut, she has extensive experience working with the CLAS and CLAS12 experiments at Jefferson Lab. Her research focuses on color propagation and hadronization in cold nuclear matter, as evidenced by her role as co-spokesperson and run coordinator for the recently realized RG-E experiment with CLAS12 at Jefferson Lab using an 11 GeV electron beam. She is further involved in simulations and physics studies for the potential upgrade of Jefferson Lab to 22 GeV. Beyond her core work at Jefferson Lab, she contributes to the SWGO astrophysics project under a Chilean government Quimal grant. Taisiya Mineeva has also held positions as Postdoctoral Fellow in the field of neutron interferometry and quantum information processing based at the National Institute for Standards and Technology (NIST), USA and as an Assistant Professor at Universidad Técnica Federico Santa María, Chile. She has authored several publications in her field, including as lead author, and holds a long-standing record of securing research funding, including multiple Chilean government FONDECYT grants.
