Two particle correlations: from RHIC to LHC

Francesco Noferini

The aim of this work is the study of two particle correlation at high and intermediate pT in order to investigate the QGP with hard probes. The experimental results, at RHIC, have shown that this kind of signals could be very interesting, even at LHC, to estimate the strenght of the jet quenching in the medium. To have some predictions of the possible scenarios which would be found at LHC, I made some simulations with PYTHIA and HIJING Monte Carlo in the framework of the Quenching Weights models, developed by Wiedemann and Salgado. These results would confirm the possibility to observe a characterize the QGP effect over the high pT signals.
