+Description:
+  Measurements of normalized differential cross-sections of top-quark pair production are presented as a function of the top-quark,
+  $t\bar{t}$ system and event-level kinematic observables in proton-proton collisions at a centre-of-mass energy of 
+  $\sqrt{s} = 8$ TeV. The observables have been chosen to emphasize the $t\bar{t}$ production process and to be sensitive to effects 
+  of initial- and final-state radiation, to the different parton distribution functions, and to non-resonant processes and higher-order 
+  corrections. The dataset corresponds to an integrated luminosity of 20.3 fb${}^{-1}$, recorded in 2012 with the ATLAS detector at the 
+  CERN Large Hadron Collider. Events are selected in the lepton$+$jets channel, requiring exactly one charged lepton and at least four 
+  jets with at least two of the jets tagged as originating from a $b$-quark. The measured spectra are corrected for detector effects and 
+  are compared to several Monte Carlo simulations. The results are in fair agreement with the predictions over a wide kinematic range.
+  Nevertheless, most generators predict a harder top-quark transverse momentum distribution at high values than what is observed in
+  the data. Predictions beyond NLO accuracy improve the agreement with data at high top-quark transverse momenta. Using the current
+  settings and parton distribution functions, the rapidity distributions are not well modelled by any generator under consideration.
+  However, the level of agreement is improved when more recent sets of parton distribution functions are used.
