HIGH pT JET PRODUCTION IN pp COLLISIONS

Production rates of large pT jets inpp collisions at RHIC and LHC energies are studied using the next-to-leading order calculation of S.D. Ellis, Z. Kunszt and D. Soper. The computed inclusive one-jet cross sections are compared against the CERN and Fermilab jet data from [Formula: see text] and pp collisions. The dependence of the results on the choice of parton distributions and renormalization/factorization scales is investigated.

AbstractThe measurement of the jet cross sections by the H1 collaboration had been compared to various predictions including the next-to-next-to-leading order (NNLO) QCD calculations which are corrected in this erratum for an implementation error in one of the components of the NNLO calculations. The jet data and the other predictions remain unchanged. Eight figures, one table and conclusions are adapted accordingly, exhibiting even better agreement between the corrected NNLO predictions and the jet data.

Inclusive Jet Production

We present a recent calculation of single-inclusive high-pT jet production in pp collisions at RHIC, when the initial protons are unpolarized and also when they are longitudinally polarized. We investigate the effect of the algorithm adopted to define the jets on the numerical results of cross sections and spin asymmetries.

During the first years of the LHC operation a large amount of jet data was recorded by the ATLAS and CMS experiments. In this review several measurements of jet-related observables are presented, such as multi-jet rates and cross sections, ratios of jet cross sections, jet shapes and event shape observables. All results presented here are based on jet data collected at a centre-of-mass energy of 7 TeV. Data are compared to various Monte Carlo generators, as well as to theoretical next-to-leading-order calculations allowing a test of perturbative Quantum Chromodynamics in a previously unexplored energy region.

We present predictions for the inclusive production of bottom jets in proton–antiproton collisions at 1.96 TeV and proton–proton collisions at 7 TeV. The bottom quark is considered massless. In this scheme, we find that at small transverse momentum [Formula: see text] the ratio of the next-to-leading order to the leading-order cross-section ([Formula: see text] factor) is smaller than one. It increases with increasing [Formula: see text] and approaches one at larger [Formula: see text] at a value depending essentially on the choice of the renormalization scale. Adding nonperturbative corrections obtained from PYTHIA Monte Carlo calculations leads to reasonable agreement with experimental [Formula: see text]-jet cross-sections obtained by the CDF and the CMS collaborations.
