摘要

The influence of initial state radiation and final state radiation on the top quark mass reconstruction in the dileptonic channel is investigated. To reconstruct the top mass the m_(T2) variable is used. Studies are performed on simulated samples produced with two Monte Carlo generators, PYTHIA 8 and POWHEG, and the detector response is modelled using the DELPHES framework. Quantitative results on Initial State Radiation, Final State Radiation and Leading Order/Next to Leading Order comparative analysis are shown.
