Abstract:
In relativistic collisions of large nuclei, a hot and dense medium referred to as the Quark Gluon Plasma (QGP) can be formed, which explodes and evaporates very soon after collisions. The long-distance behavior of such a medium resembles a liquid, and its inner working is still an open question. In this talk I will explain how we can probe the QGP using streams of energetic particles produced in hard collisions known as jets. These jets penetrate the QGP, and through strong interactions, the substructure of jets can tell us information about short-distance medium properties. The upcoming data from Relativistic Heavy Ion Collider at Brookhaven National Laboratory and the Run 3 of the Large Hadron Collider at the European Organization for Nuclear Research will hopefully shed light on the microscopic picture of the QGP. A path toward the future Electron Ion Collider is being planned, which will provide essential information about nuclear structure as initial condition of the QGP formation.
