Jet and photon physics
Marco Peruzzi (for the ATLAS, CMS Collaborations)
TL;DR
This paper reviews jet and photon production measurements at the LHC, highlighting their importance for testing QCD, constraining parton distribution functions, and understanding higher-order effects in proton-proton collisions.
Contribution
It summarizes recent experimental results from ATLAS and CMS on jet and photon production and discusses their implications for QCD and theoretical models.
Findings
Jet measurements agree with QCD predictions within uncertainties.
Photon production is highly sensitive to higher-order QCD corrections.
Results provide valuable input for parton distribution functions and strong coupling constant.
Abstract
Jet production in proton-proton collisions is one of the main phenomenological predictions of QCD. The ATLAS and CMS Collaborations have performed measurements of several jet observables at the LHC and compared their results to theoretical predictions and event generators. Useful physics input for the determination of the parton distribution functions and the strong coupling constant is provided. Photon production measurements represent another important test of QCD and show strong sensitivity to higher-order corrections.
