Description
This article introduces definitions for a number of new event shapes and jet-rates in hadron-hadron dijet production. They are designed so as to be measurable in practice at the Tevatron and the LHC, and to be global so that they can be resummed with currently available techniques. We explain how to vary their sensitivity to beam fragmentation, limiting its impact for purely perturbative studies, or deliberately enhancing it so as to focus on non-perturbative effects. Explicit next-to-leading logarithmic resummed results are presented, as obtained with CAESAR.
33 pages, 14 figures, JHEP class included. Other results obtained with CAESAR are available at http://qcd-caesar.org. v2 includes extra references and clarifications in the discussions of prior work, as well as additional analytical information in the tables of properties of observables. v3 corrects figures 9 and 13 so as to correspond to cuts described in the text, corrects a misprint in caption of figure 10 and has improved versions of figures 5,7,8,10
