| Abstract: | The double differential cross sections of the Drell–Yan lepton pair ( ℓ + ℓ - , dielectron or dimuon) production are measured as functions of the invariant mass m ℓ ℓ , transverse momentum p T (ℓ ℓ) , and φ η ∗ . The φ η ∗ observable, derived from angular measurements of the leptons and highly correlated with p T (ℓ ℓ) , is used to probe the low- p T (ℓ ℓ) region in a complementary way. Dilepton masses up to 1 Te V are investigated. Additionally, a measurement is performed requiring at least one jet in the final state. To benefit from partial cancellation of the systematic uncertainty, the ratios of the differential cross sections for various m ℓ ℓ ranges to those in the Z mass peak interval are presented. The collected data correspond to an integrated luminosity of 36.3 fb - 1 of proton–proton collisions recorded with the CMS detector at the LHC at a centre-of-mass energy of 13 Te V . Measurements are compared with predictions based on perturbative quantum chromodynamics, including soft-gluon resummation. [ABSTRACT FROM AUTHOR] |
