“…The difference between azimuthal angles (∆φ) [7] of the two jets in a dijet system (expected to peak at ∆φ ∼ π for back-to-back dijets at LO) can serve for testing NLO predictions without actually measuring additional jets. It can also serve for tuning parton shower Monte Carlo generators.…”

This thesis describes the measurement of the inclusive three-jet cross section in proton-antiproton collisions at √ s = 1.96 TeV measured at the DØ experiment at the Fermilab Tevatron Collider in the Fermi National Accelerator Laboratory, Batavia, Illinois, USA. The cross section as a function of threejet invariant mass is provided in three regions of the third jet transverse momentum and three regions of jet rapidities. It utilizes a data sample collected in the so called Run IIa data taking period (2002)(2003)(2004)(2005)(2006) corresponding to the integrated luminosity of about 0.7 fb −1 . The results are used to test the next-to-leading order predictions of Quantum chromodynamics computed using the latest parton distribution functions.

A parton-shower model for hadronic collisions based on the emission properties of QCD dipoles is proposed. This proposal therefore extends the well-known radiation pattern of pure final-state colour dipoles to QCD initial-state radiation, both of which are treated perturbatively. Corresponding dipole splitting functions are derived and the kinematics of all dipole splittings is discussed. The application of the resulting dipoleshower model to hadron production in electron-positron annihilation, to Drell-Yan leptonpair and QCD jet production yields encouraging results.

“…In proton-proton collisions a small acoplanarity appears due to intrinsic transverse momentum k T from partonic Fermi motion [1] and initial state gluon radiation [2,3]. At large momentum transfer between the incoming partons, the phase space for hard gluon radiation in the parton shower or from next-to-leading-order (NLO) processes increases, resulting in acoplanarity of the dijet system [4][5][6]. This also results in an imbalance of the jet transverse momenta also referred to as a broadening of the dijet transverse momentum.…”

A measurement of dijet correlations in p-Pb collisions at √ s NN = 5.02 TeV with the ALICE detector is presented. Jets are reconstructed from charged particles measured in the central tracking detectors and neutral energy deposited in the electromagnetic calorimeter. The transverse momentum of the full jet (clustered from charged and neutral constituents) and charged jet (clustered from charged particles only) is corrected event-by-event for the contribution of the underlying event, while corrections for underlying event fluctuations and finite detector resolution are applied on an inclusive basis. A projection of the dijet transverse momentum, k Ty = p ch+ne T,jet sin( ϕ dijet ) with ϕ dijet the azimuthal angle between a full and charged jet and p ch+ne T,jetthe transverse momentum of the full jet, is used to study nuclear matter effects in p-Pb collisions. This observable is sensitive to the acoplanarity of dijet production and its potential modification in p-Pb collisions with respect to pp collisions. Measurements of the dijet k Ty as a function of the transverse momentum of the full and recoil charged jet, and the event multiplicity are presented. No significant modification of k Ty due to nuclear matter effects in p-Pb collisions with respect to the event multiplicity or a PYTHIA8 reference is observed.
