Abstract
The Quark Gluon Plasma (QGP) is a hot, dense state of matter in which the Quarks and Gluons that make up Hadrons are freed. The QGP is theorized to be similar to the conditions during the first few milliseconds of the universe. The LHC can create QGP via the collision of Lead(Pb) ions at ultra relativistic velocities. The QGP is short lived so external probes cannot be used to glean information. So instead we turn to internal probes such as jets, sprays of particles from a hard scattering of quarks and gluons, to test the medium. It is expected that Proton-Proton (pp) collisions do not generate a QGP so by comparing the jet observables in PbPb and pp collisions, we can gain information about the medium. One method of determining the properties of the medium is to compare data with Monte Carlo (MC) simulations of collisions and vary the model parameters. In this presentation I will discuss different MC generators with a particular focus on the Jewel Generator. I will present MC results in comparison to data for Jet Observables such as the 3 Jet to 2 Jet event ratio. The next steps include using PbPb data in addition to MC simulations and running the simulated events through a simulation of the detectors and reconstructing using the algorithms applied to data.
