Research Interests: Experimental Nuclear and Particle Physics

I am interested to the study of the internal structure of the strongly interacting particles, hadrons. This research is carried out at Jefferson Laboratory (JLab), Newport News, VA, and Fermi National Laboratory (Fermilab), Batavia, IL. Currently, I am involved in several 6 GeV data analyses projects at JLab that aim to study the Deeply Virtual Compton Scattering off 4He in addition to the meson spectroscopy in the 4He coherent production (EG6 experiment "internal wiki-page"), extract a high precision nucleon spin structure at very low momentum transfer to test various spin sum rules (EG4 experiment "internal wiki-page"), and probe the time evolution of elementary configurations of the hadron wave function via the hadronization study of the Λ0 baryon (EG2 experiment; "Color Transparency" and "Quark Propagation" measurements). The latter provides a promising method to investigate nucleon and nuclear structure, construct a theory of super-dense nuclear matter, and disentangle the physics of heavy ion collisions that takes place at high temperatures with the creation of a Quark-Gluon Plasma. The ongoing analysis results will be further enriched once the approved hadronzation program will run after accomplishing the 12 GeV upgrade of the JLab beam energy. To support the ongoing upgrade effort of CLAS12, housed at Hall-B, JLab, my group is part of the team developing the drift chambers calibration and debugging software that will be used in the 12 GeV era.

On the other hand, my Fermilab research focuses on the Drell-Yan experiment (dubbed SeaQuest). This new measurement aims to extract a more precise anti-quark asymmetry ratio, study the quark propagation and energy loss effects in the cold nuclear matter, target nucleus, before the hard process, di-lepton production, takes place, in addition to the measurement of Drell-Yan cross sections from several nuclear targets to compare the sea quark distribution in nuclei to that in Deuterium. The latter will allow an examination of the previously published Drell-Yan, which showed no significant modification of the nuclear cross section for longitudinal momentum fraction, x > 0.1, unlike the "anti-shadowing" enhancement observed in the deep inelastic scattering and the European Muon Collaboration (EMC) experiments. The SeaQuest data will be able to address the question of whether the anti-shadowing region and the so-called "EMC" effect (depletion seen for x ~ 0.5) exist in the Drell-Yan process.
