Measurement of the inclusive differential jet cross section in pp collisions at sqrt{s} = 2.76 TeV

Measurement of the inclusive differential jet cross section in pp collisions at sqrt{s} = 2.76 TeV

The ALICE collaboration at the CERN Large Hadron Collider reports the first measurement of the inclusive differential jet cross section at mid-rapidity in pp collisions at sqrt(s) = 2.76 TeV, with integrated luminosity of 13.6 nb^-1. Jets are measured over the transverse momentum range 20 to 125 GeV...

Zusammenfassung:The ALICE collaboration at the CERN Large Hadron Collider reports the first measurement of the inclusive differential jet cross section at mid-rapidity in pp collisions at sqrt(s) = 2.76 TeV, with integrated luminosity of 13.6 nb^-1. Jets are measured over the transverse momentum range 20 to 125 GeV/c and are corrected to the particle level. Calculations based on Next-to-Leading Order perturbative QCD are in good agreement with the measurements. The ratio of inclusive jet cross sections for jet radii R = 0.2 and R = 0.4 is reported, and is also well reproduced by a Next-to-Leading Order perturbative QCD calculation when hadronization effects are included.
