Abstract
In this article, a model based on Glauber Monte Carlo is built to simulate the procedure of jet quenching in Quark-Gluon Plasma (QGP). In this model, energy loss of jets in QGP is parametrized by two quantities: path length of jets in QGP, L, and the initial transverse momentum of the jet P T . The path length of each branch of the jet are labeled L 1 and L 2 . As input data, original jet energy data of p + p collisions were obtained from CMS measurement. After being processed by our model, simulated Pb + Pb jet energy data could be given and were compared to the data of ATLAS’s measurement in Ref. [1]. Distributions of (1/N)dN/dx <sub>J</sub> where x <sub>J</sub>=P<sub>T2</sub>/P<sub>T1</sub>, also noted as “frequency”, are presented as a function of P T1 and collision centrality. As the final result, two different forms of energy loss formula were found, both of which have good adaptation to certain centrality and P T ranges.
