Parton shower Monte Carlos vs Resummed calculations for interjet energy flow observables

    Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

    Abstract

    Parton showers in Monte Carlo event generators reflect to a certain accuracy our understanding of QCD radiation at all orders. For interjet energy flow observables it has been known for some time that relevant all-order dynamics is substantially more complicated than that encoded via angular ordering in parton shower algorithms, even to leading logarithmic accuracy. Here we investigate the extent of the numerical mismatch between leading logarithmic analytical estimates (resummation) and parton showers in an effort to better understand the accuracy of parton showers for such observables.
