Event shapes at hadron colliders

Abstract

We present precision results for distributions in global event shapes that can be measured at hadron colliders within experimental limitations. These predictions are obtained by combining exact next-to-leading order (NLO) with the all-order resummation of large logarithms of soft and collinear origin. We then discuss how event-shape measurements can be used for the tuning of Monte Carlo event generators, for tests of models of hadronisation and underlying event, and as discriminatory tools between QCD jet-like and New Physics events.
