Description

Experimental data measured in $\sqrt{s}$ = 2.76 ATeV Pb+Pb collisions by the LHC experiments show a significant imbalance in the transverse momenta of the two leading reconstructed jets. This momentum imbalance is caused by the different in-medium path lengths and thereby different energy and momentum losses of the di-jets due to the passage through the created hot and dense matter. For investigating this momentum loss we extended the partonic transport model BAMPS which solves the full 3+1D Boltzmann equation for partons based on pQCD cross sections. Among the features of BAMPS is the stochastic modeling of both 2->2 and 2<->3 scattering processes by employing a new, improved Gunion-Bertsch matrix element together with a microscopic running coupling. In this talk we compare our recent results concerning reconstructed jets with different experiments and observables. To this end, we use well-established experimental background subtraction methods and have a closer look at the influence of the further recoil scattering processes of the initial shower partons on the momentum loss of the reconstructed jets.
