Triple-differential measurement of the dijet cross section at √s = 13 TeV with the CMS detector — Günter Quast, Klaus Rabbertz, and •Daniel Savoiu — Karlsruher Institut für Technologie (KIT)
Jet cross sections are of particular interest for precision studies at proton colliders such as the LHC. They are sensitive to the proton structure and can be used to derive tighter constraints on the parton distribution functions (PDFs) of the proton. Moreover, jet production is among the processes with the highest cross section. As a result, event rates are high enough to enable differential measurements as a function of multiple observables with sufficient statistical precision.
The analysis presented here concerns a triple-differential measurement of the dijet production cross section from data collected by the CMS experiment during Run 2 of the LHC at a center-of-mass energy of 13 TeV. The cross section is measured as a function of the dijet rapidity difference y*, the total boost of the dijet system yb, and the average transverse momentum of the jets. An alternative measurement is performed using the dijet invariant mass as the third variable.
