Measurements of top-quark pair differential and double-differential cross-sections in the ℓ+jets channel with pp collisions at √ s = 13 TeV using the ATLAS detector Aad, G. Aguilar Saavedra, Juan Antonio Atlas Collaboration Single- and double-differential cross-section measurements are presented for the production of top-quark pairs, in the lepton + jets channel at particle and parton level. Two topologies, resolved and boosted, are considered and the results are presented as a function of several kinematic variables characterising the top and t ¯t system and jet multiplicities. The study was performed using data from pp collisions at centre-of-mass energy of 13 TeV collected in 2015 and 2016 by the ATLAS detector at the CERN Large Hadron Collider (LHC), corresponding to an integrated luminosity of 36 fb−1. Due to the large t ¯t cross-section at the LHC, such measurements allow a detailed study of the properties of top-quark production and decay, enabling precision tests of several Monte Carlo generators and fixed-order Standard Model predictions. Overall, there is good agreement between the theoretical predictions and the data. 2020-01-10T08:49:59Z 2020-01-10T08:49:59Z 2019-12-24 info:eu-repo/semantics/article Aad, G., Abbott, B., Abbott, D.
