A simple description of jet cross-section ratios
arXiv:1101.2665 · doi:10.1016/j.physletb.2011.02.061
Abstract
We compute the ratio of the inclusive jet cross-sections obtained with the same jet algorithm at two different values of the jet radius. We perform a computation of that observable at NLO (O(alphas^2)) in perturbative QCD and compute non-perturbative corrections from soft-gluon emission. We discuss predictions for RHIC and the LHC.
