Jet production in the very forward direction at 13 TeV with CMS

The new frontier collision energy s=13TeV of the Large Hadron Collider (LHC) at the Run II has important key points in particle physics. Forward jets, abundantly produced in proton-proton (pp) collisions, are useful tools to test Quantum Chromodynamics (QCD) predictions at low values of parton momentum fraction x. Measurement of the differential inclusive jet production cross section in the very forward direction is a powerful benchmark to study multiple partonic interactions (MPI) in pp collisons. The very forward jet measurement is performed with the CMS detector in a special early run at 13 TeV taken with B = 0 T. The results are corrected to stable particle level and compared to several Monte Carlo (MC) model predictions.
