The DZERO detector is used to study proton-antiproton collisions at the 1800 GeV and 630 GeV center-of-mass energies available at the Fermilab Tevatron. To measure jets, the detector uses a sampling calorimeter composed of uranium and liquid argon as the passive and active media respectively. Understanding the jet energy calibration is not only crucial for precision tests of QCD, but also for the measurement of particle masses and the determination of physics backgrounds associated with new phenomena. This paper describes the energy calibration of jets observed with the DZERO detector at the two proton-antiproton center-of-mass energies in the transverse energy and pseudorapidity range ET>8 GeV and pseudorapidity<3.
We study the impact of new set of cuts, proposed in our previous works, on the improvement of accuracy of the jet energy calibration with p p ->photon+Jet+X process at LHC. Monte Carlo events produced by the PYTHIA 5.7 generator are used for this aim
A possibility of jet energy scale setting by help of ``p p -> Z0+jet+X process at LHC is studied. The effect of new set of cuts, proposed in our previous works, on the improvement of the Pt balance between Z0 boson and jet is demonstrated. The distri
The consequences of application of new set of criteria, proposed in our previous works, for the improvement of a jet energy calibration accuracy with the process p~p->photon+jet+X at Tevatron and for a reduction of background events contribution are
Jets originating from the fragmentation of quarks and gluons are the most common, and complicated, final state objects produced at hadron colliders. A precise knowledge of their energy calibration is therefore of great importance at experiments at th
The article describes the identification of hadronically decaying tau leptons in ppbar collisions at 1.96 TeV collected by the DZero detector at the Fermilab Tevatron. After a brief description of the motivations and the challenges of considering tau
