Measurement of the triple differential inclusive Z (→µµ) + 1 jet cross section at √s=13 TeV with the CMS detector and constraints on the proton structure — •Thomas Berger, Klaus Rabbertz, and Günter Quast — Karlsruher Institut für Technologie
This talk presents a measurement of the triple differential inclusive Z(→µµ) + 1 jet cross section in proton-proton collisions at the LHC at √s=13 TeV. The data represent an integrated luminosity of 35.8 fb−1 collected with the CMS detector in 2016. The cross section is measured as a function of the Z boson’s transverse momentum pTZ, the rapidity separation y* of the Z boson and the leading jet, and the boost yb of their center-of-mass system. The analysis is performed simultaneously with a variable Φη* determined from muon angular information. Cross section predictions have been derived at next-to-next-to-leading order. The measured cross sections are corrected for detector effects and compared with the predictions to obtain constraints on the parton distribution functions of the proton.
