Measurement of Triple-Differential Dijet Cross Sections with the CMS Detector at 8 TeV and PDF Constraints
Abstract (englisch):
The first measurement of triple-differential dijet cross sections at the LHC is presented using 19.71 fb⁻¹ of data collected with the CMS detector in proton-proton collisions at 8 TeV. The unfolded cross sections agree with perturbative QCD calculations at NLO accuracy. Constraints on the PDFs are derived. Compared to a fit with HERA DIS data alone, the uncertainties of the PDFs, especially those of the gluon PDF, are significantly reduced and a harder gluon PDF is obtained.
