Título: | Measurement of the transverse momentum distribution of Drell–Yan lepton pairs in proton–proton collisions at √s=13 TeV with the ATLAS detector | Autor: | Fiolhais, M. C. N. Veloso, F. Wolters, H. ATLAS Collaboration |
Data: | 2020 | Editora: | Springer Nature | Título da revista, periódico, livro ou evento: | European Physical Journal C | Volume: | 80 | Número: | 7 | Resumo: | This paper describes precision measurements of the transverse momentum p T ( = e,μ) and of the angular variable φ ∗ η distributions of Drell–Yan lepton pairs in a mass range of 66–116 GeV. The analysis uses data from 36.1 fb−1 o√f proton–proton collisions at a centre-of-mass energy of s = 13 TeV collected by the ATLAS experiment at the LHC in 2015 and 2016. Measurements in electron-pair and muon-pair final states are performed in the same fiducial volumes, corrected for detector effects, and combined. Compared to previous measurements in proton–proton collisions at √ s = 7 and 8 TeV, these new measurements probe perturbative QCD at a higher centre-of-mass energy with a different composition of initial states. They reach a precision of 0.2% for the normalized spectra at low values of p T . The data are compared with different QCD predictions, where it is found that predictions based on resummation approaches can describe the full spectrum within uncertainties. | URI: | https://hdl.handle.net/10316/106043 | DOI: | 10.1140/epjc/s10052-020-8001-z | Direitos: | openAccess |
