 A study of the sensitivity to the Pythia8 parton shower parameters of $t\bar{t}$ production measurements in $pp$ collisions at $\sqrt{s} = 7$ TeV with the ATLAS experiment at the LHC Various measurements of $t\bar{t}$ observables, performed by the ATLAS experiment in $pp$ collisions at $\sqrt{s} = 7$ TeV, are used to constrain the initial- and final-state radiation parameters of the Pythia8 Monte Carlo.
