Measuring jets with ALICE

The rate of jets expected in ALICE was determined using PYTHIA. We first calculated the inclusive jet cross section in pp̄ collision at √ s=1.8 TeV and compared it to the data of the D0 experiment[1]. As shown in Fig. 1, the PYTHIA calculation, up-scaled by K=1.5, describes the data reasonably well. The calculation was performed in three runs differing by the value of the CKIN(50) parameter which defines the minimum momentum transfer, i.e. the “hardness” of a collision. The three curves, corresponding to CKIN(3) of 50, 100, and 200 GeV, nicely match in overlap regions. The CTEQ4HJ structure function was used.
