Initial and final state radiation studies for top quark mass reconstruction in dileptonic channel for square s=7 TeV p-p collisions

摘要

The influence of initial state radiation and final state radiation on the topquark mass reconstruction in the dileptonic channel is investigated. To reconstruct thetop mass the mT2 variable is used. Studies are performed on simulated samplesproduced with two Monte Carlo generators, PYTHIA 8 and POWHEG, and the detectorresponse is modelled using the DELPHES framework. Quantitative results on InitialState Radiation, Final State Radiation and Leading Order/Next to Leading Ordercomparative analysis are shown.
