Description
The Quark-Gluon Plasma (QGP) is predicted to be the predominant state of matter at a few microseconds after the Big Bang, being the earliest stage of the Universe known so far. This state of QCD matter can be produced in ultra-relativistic heavy ion collisions, such as those in the Large Hadron Collider (LHC) or in the Relativistic Heavy-Ion Collider (RHIC). Since this medium is very short-lived, the QGP characteristics can only be infer by the products of heavy ion collisions. One example of the indirect probes used in this study are the jets – collimated spray of energetic hadrons. These objects propagate in the QGP and interact with it by losing energy. This means that the jet is expected to be modified or absorbed by the QGP, in a phenomena known as jet quenching. By using observables which compare unmodified objects in the QGP with quenched jets, one can study the energy loss in the medium.
