Abstract

Absolute and normalised differential cross-sections of single top quarks\nproduced in the t-channel are presented. 20.2 fb^-1 of proton-proton\ncollision data at a centre-of-mass energy of 8 TeV collected by the ATLAS\nexperiment at the LHC are used. Differential cross-sections as a function of\nthe transverse momentum and the absolute value of the rapidity of the top\nquarks and the top antiquarks are measured at both parton level and particle\nlevel. The transverse momentum and rapidity differential cross-sections of the\nscattered light-quark jets are extracted at particle level. The measured\ncross-sections are compared to various Monte Carlo predictions as well as to\navailable fixed-order QCD calculations. All results agree with the Standard\nModel predictions.\n
