Abstract
The energy loss during jet quenching due to the existence of Quark Gluon Plasma (QGP) is calculated by Optical Glaube Monte Carlo model with data collected by ATLAS Collaboration using the LHC detector. An energy loss formula for this situation was modeled and took the form . The nuclear modification factor, R AA , for jets in a 208 Pb + 208 Pb nucleus collision with rapidity interval of ∣ у ∣ =2.8 and the initial transverse momentum of 50 GeV ≤ p T ≤ 1000 GeV , are compared with various data plots produced by ATLAS Collaboration. R AA results are plotted in different centrality bins, which are defined by the distribution of number of participating nucleons N part . The R AA value was found to slowly increase at lower transverse momenta and flatten out at higher transverse momenta. The model ’ s theoretical calculation results turned out to be similar to the plots produced by the ATLAS Collaboration using data from the LHC with small differences for higher systematic uncertainty events.
