Abstract
The Compact Muon Solenoid (CMS) is one of the two large multipurpose experiments at the LHC. We present the CMS results related to tests of QCD predictions for jet, dijet, and multijet production in pp collisions at center-of-mass energies of 7 TeV and 8 TeV. The results also include recent hadronic event shape measurements, as extraction, charged hadron measurements, dijet azimuthal decorrelations, searches for BFKL effects in the azimuthal correlations of forward-backward and forward-central jets at 7 TeV, and studies of the transition from the perturbative to the non-perturbative regime using minijets at 8 TeV.
Highlights
Events with collimated streams of particles, called jets, are abundantly produced in high energetic proton-proton collisions at the LHC
We present the Compact Muon Solenoid (CMS) results related to tests of Quantum Chromodynamics (QCD) predictions for jet, dijet, and multijet production in pp collisions at center-of-mass energies of 7 TeV and 8 TeV
Such events can be described by Quantum Chromodynamics (QCD) in terms of parton-parton scattering where the outgoing scattered partons manifest themselves as hadronic jets
Summary
Events with collimated streams of particles, called jets, are abundantly produced in high energetic proton-proton collisions at the LHC. We present the CMS results related to tests of QCD predictions for jet, dijet, and multijet production in pp collisions at center-of-mass energies of 7 TeV and 8 TeV. The results include recent hadronic event shape measurements, αs extraction, charged hadron measurements, dijet azimuthal decorrelations, searches for BFKL effects in the azimuthal correlations of forward-backward and forward-central jets at 7 TeV, and studies of the transition from the perturbative to the non-perturbative regime using minijets at 8 TeV.
