Measurement of the mass dependence of the transverse momentum of lepton pairs in Drell-Yan production in proton-proton collisions at s=13TeV. Academic Article uri icon

abstract

  • The double differential cross sections of the Drell-Yan lepton pair (+-, dielectron or dimuon) production are measured as functions of the invariant mass m, transverse momentum pT(), and . The observable, derived from angular measurements of the leptons and highly correlated with pT(), is used to probe the low-pT() region in a complementary way. Dilepton masses up to 1TeV 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 ranges to those in the Z mass peak interval are presented. The collected data correspond to an integrated luminosity of 36.3fb-1 of proton-proton collisions recorded with the CMS detector at the LHC at a centre-of-mass energy of 13TeV. Measurements are compared with predictions based on perturbative quantum chromodynamics, including soft-gluon resummation.
