Results from D0: dijet angular distributions, dijet mass cross section and dijet azimuthal decorrelations

PDF Version Also Available for Download.

Description

Several tests of Quantum chromodynamics (QCD) in the inclusive dijet final state from the D0 experiment at the Fermilab Tevatron Collider are presented. At hadron colliders, jet production has one of the highest cross section and is therefore an ideal place to test the predictions of perturbative Quantum chromodynamics (pQCD). The difference in the azimuthal angle of the two jet system ({Delta}{phi}), the {chi}{sub dijet} variable related to the polar angle of the dijet system ({chi}{sub dijet} = exp(y{sub 1}-y{sub 2}), where y{sub 1,2} are the rapidities y = 0.5ln(E + p{sub z})/(E - p{sub z}) of the two jets, ... continued below

Description

Several tests of Quantum chromodynamics (QCD) in the inclusive dijet final state from the D0 experiment at the Fermilab Tevatron Collider are presented. At hadron colliders, jet production has one of the highest cross section and is therefore an ideal place to test the predictions of perturbative Quantum chromodynamics (pQCD). The difference in the azimuthal angle of the two jet system ({Delta}{phi}), the {chi}{sub dijet} variable related to the polar angle of the dijet system ({chi}{sub dijet} = exp(y{sub 1}-y{sub 2}), where y{sub 1,2} are the rapidities y = 0.5ln(E + p{sub z})/(E - p{sub z}) of the two jets, E is the jet energy and p{sub z} is the jet momentum along the beam line) and dijet invariant mass M{sub jj} are presented. Several interesting dijet variables were measured by the DO collaboration in the Run II of the Tevatron Collider. The measurements are well described by the NLO predictions of QCD and the {chi}{sub dijet} sets the best limits in some models beyond the Standard model.
