Sumario:Absolute and normalised differential cross-sections of single top quarks produced in the $t$-channel are presented. 20.2 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 8 TeV collected by the ATLAS experiment at the LHC are used. Differential cross-sections as a function of the transverse momentum and the absolute value of the rapidity of the top quarks and the top antiquarks are measured at both parton level and particle level. The transverse momentum and rapidity differential cross-sections of the scattered light-quark jets are extracted at particle level. The measured cross-sections are compared to various Monte Carlo predictions as well as to available fixed-order QCD calculations. All results agree with the Standard Model predictions.
