Measurement of the mass dependence of the transverse momentum of lepton pairs in Drell-Yan production in proton-proton collisions at [Formula omitted]

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