Quark-Gluon Plasma
Abstract in English
In this work, we investigate possible impacts that the behavior of the Quark-Gluon Plasma might have on Jet Observables. We choose JEWEL (Jet Evolution With Energy Loss) for this study. We have coupled JEWEL with TRENTo and also with MC-KLN+vUSPhydro for sim- ulations. The simulations were performed for PbPb collisions at sN N = 2.76 TeV in the 0 10% centrality class. We have found that jet shape observables are mainly unchanged by the inclusion of realistic hydrodynamics and initial conditions in these settings. We also made calculations for the jet v2. In this case, we have found that initial conditions do not affect this observable. In the case of realistic hydrodynamics, there is an improvement in the description of data.

Abstract in Portuguese
Neste trabalho nos investigamos possveis impactos que o plasma de Quarks e Gluons pode ter nos observaveis de Jatos. Nos escolhemos o JEWEL (Jet Evolution With Energy Loss) para este estudo. Nos acoplamos o JEWEL com o modelo TRENTo e tambem com o MC- KLN+vUSPhydro para as simulacoes. As simulaoes foram realizadas para colisoes chumbo- chumbo a energia sN N = 2.76 TeV para centralidade 010%. Nessas condicoes, observaveis de forma e geometria dos jatos nao sao modificados pela implementacao de uma hidrodinamica e condicoes iniciais realistas. Tambem calculamos o v2 dos jatos. Neste caso nos conclumos que as condicoes iniciais tambem nao afetam esse observavel. No caso da hidrodinamica realista, houve uma melhoria na descricao desse observavel.
