Measurement of the triple differential inclusive Z (→ µ µ) + jet cross section at √s=13 TeV using 2016 and 2017 data from the CMS detector — Thomas Berger, Maximilian Horzela, Günter Quast, Klaus Rabbertz, and •Matthias Schnepf — Karlsruhe Institute of Technology
The proton structure, which is not perturbatively calculable, is a limiting uncertainty in many LHC analyses. Therefore, precise experimental measurements to determine the proton structure in the form of the parton distribution functions (PDFs) are primarily important.
The Z(→ µ µ) boson production in association with Jets provides a combination of high event rates and clear signals. We give an overview of a triple differential inclusive Z(→ µ µ)+jet cross section measurement at √s=13 TeV with data taken by the CMS detector in 2016 and 2017. The cross section is measured as a function of the rapidity separation of the Z boson and the leading jet, the boost of their center-of-mass system, and the transverse momentum of the Z boson (pTZ). Furthermore, the measurement is alternatively performed with a variable determined from muon angular information instead of pTZ. The results are compared with next-to-next-to-leading order calculations.
