Descripción
Normalized differential cross sections for top quark pair production are
measured in the dilepton (e+e-, μ +
μ -, and μ ∓e±)
decay channels in proton-proton collisions at a center-of-mass energy of
13 TeV. The measurements are performed with data corresponding to an
integrated luminosity of 2.1 fb-1 using the CMS detector at
the LHC. The cross sections are measured differentially as a function of
the kinematic properties of the leptons, jets from bottom quark
hadronization, top quarks, and top quark pairs at the particle and
parton levels. The results are compared to several Monte Carlo
generators that implement calculations up to next-to-leading order in
perturbative quantum chromodynamics interfaced with parton showering,
and also to fixed-order theoretical calculations of top quark pair
production up to next-to-next-to-leading order. [Figure not available:
