The performance of the jet identification and reconstruction in heavy ions collisions with CMS detector

A jet reconstruction algorithm is developed for events with a high particle density in the calorimetric system. The performance of the reconstruction of hard QCD jets with initial parton energies 50–300 GeV is studied in central Pb–Pb collisions with a modified cone jet finder which includes an algo...

description A jet reconstruction algorithm is developed for events with a high particle density in the calorimetric system. The performance of the reconstruction of hard QCD jets with initial parton energies 50–300 GeV is studied in central Pb–Pb collisions with a modified cone jet finder which includes an algorithm for event-by-event background subtraction. The heavy ion background is simulated using the HIJING Monte Carlo generator with \(\text{d} N_{\text{ch}}/\text{d} y\vert_{y=0} = 5000\). Results on the achieved jet reconstruction efficiency, purity, energy and spatial resolution are presented.
