Sumario:In the last years, the interest in quark-gluon plasma has increased. In this thesis, we developed a way to better understand the QGP through an effect called jet quenching. We simulated two types of particle collisions. One with a Pythia sample that resembles hard scattering events in a vacuum and one with a Hybrid sample, that resembles hard scattering events in a QGP. With the production points of the jets from the Hybrid sample we made a selection for in- and outgoing jets at the edge of the QGP and outgoing jets produced near the centre. We compared four jet substructure observables in the different cases. We studied the way different observables were affected by the medium and in which case most jet quenching effects took place. We expected the outgoing jets from the Hybrid sample to look like the Pythia sample and the ingoingjets to undergo most jet quenching effects. We found that the ingoing jets from the hybrid sample looked more like the Pythia results and the jets produced near the centre where the most quenched jets. The ingoing jets were not the most quenched since the cooling of the QGP was not taken into account
