Exploring jet time-structure for QGP studies"

S@INT Seminar

The physics program of ultra-relativistic heavy-ion collisions at the Large Hadron Collider (LHC) and Relativistic Heavy-Ion Collider (RHIC) has brought a unique insight into the hot and dense QCD matter created in such collisions, the Quark-Gluon Plasma (QGP). Jet quenching, a collection of medium-induced modifications of the jets' internal structure that occur through their development in dense QCD matter, has a unique potential to assess the time structure of the produced medium. In this work, we perform an exploratory study to identify jet reclustering tools that can potentiate future QGP tomographic measurements with jets at current energies. By using the inverse of formation time to obtain the jet clustering history, one can identify the QCD parton shower more accurately, even in the presence of in-medium QGP interactions. The results can be further used to select different magnitudes of jet quenching, thus contributing to an accurate evaluation of the QGP parameters.
