Abstract
The double differential cross sections of the
Drell–Yan lepton pair ( + −, dielectron or dimuon) produc tion are measured as functions of the invariant mass m ,
transverse momentum pT( ), and ϕ∗
η . The ϕ∗
η 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 1 TeV
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 36.3 fb−1 of
proton–proton collisions recorded with the CMS detector at
the LHC at a centre-of-mass energy of 13 TeV. Measurements
are compared with predictions based on perturbative quantum chromodynamics, including soft-gluon resummation.
