Abstract:
Jet Production in Hadron-Hadron Collisions at High Energies
We investigated the effects of jet production on the following parameters: multiplicity,
pseudorapidity, transverse momentum and transverse mass distributions of charged
particles produced in hadron-hadron collisions at 1.8 TeV, centre of mass energy, using
the Dubna version of HIJING model. These distributions are analyzed for the whole
range and for six selected regions of the polar angle (angle of the secondary particles with
respect to the beam axis) as a function of number of jets. The results for the charged
particles multiplicity distributions were compared with experimental ones coming from
the SPS and Tevatron experiments and the increase in the multiplicity of the charged
particles influenced by multi-jet events is discussed. The results for pseudorapidity
distributions are interpreted and discussed in connection to the increase observed in the
multiplicity of charged particles as a result of its multi-jet dependence and are also
discussed in comparison with the experimental results coming from the CDF
Collaboration. The analysis of effect of the multi-jet events on the transverse momentum
and transverse mass distributions is also discussed in connection to the increase in the
multiplicity and pseudorapidity density of charged particles. We concluded that high
multiplicity regions, the increased pseudorapidity density and the high pT regions
correspond mainly to the multi-jet events.
