Research

My initial research focused on the Quantum Chromodynamic (QCD) phase structure, and initial-state fluctuations, of nuclear systems at moderately-high temperatures and high baryon-number densities; using an effective-Lagrangian field theory model constrained by nuclear matter properties like the binding energy, the saturation density, the symmetry energy, the (in)compressibility etc.; and on reconciling the obtained results with experiments (proposed, completed and running), by using dynamic models like the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model.
Currently, my research involves quantum statistical correlation measurements in high-energy physics, as important tools to obtain information about the space-time structure of the particle-emitting source. There are several final-state effects that modify the measured femtoscopic correlation functions by affecting the trajectory of the particles. These Aharonov-Bohm-like effects - in the sense that possible paths of a pair represent a closed loop with an internally present field - which might play a role in the modification of the strength of the Bose-Einstein correlation functions; are investigated with a toy model and a measurable quantity, sensitive to the effects, is proposed from the model simulations.
Additionally, I'm carrying out the analysis of pair-correlation data - collected by the RHIC STAR experiment at the Brookhaven National Laboratory (BNL) - in order to determine the kaon source's shape and size, from Lévy fits to the aforementioned data. The project requires a coded analysis of the raw data obtained from STAR to pin-point the correlated pairs of kaons, which are then investigated further towards the end-goal.
