Jet Production Cross Section Measurement In √ s = 5.02 Tev pp Collisions

Abstract

The study of jets offers insights into the nature of the basic partons composing matter, and enables further studies into the nature of the universe. This analysis presents the double-differential production cross section of radius parameter R = 0.3 proton-proton jets in units of pseudorapidity and transverse momentum at √ s = 5.02 TeV, measured in the Compact Muon Solenoid detector at the Large Hadron Collider experiment located at CERN. Jets are reconstructed using Particle Flow and the anti-kT algorithms. The methodology of correcting the detector response through Jet Energy Corrections and Bayesian unfolding is described with a detailed explanation. The results from data recorded in CMS in 2015 are shown and compared with leading-order theory-based simulated PYTHIA8 Monte Carlo events.
