The resummation of inter-jet energy flow for gaps-between-jets processes at HERA
R. B. Appleby, M. H. Seymour
Abstract
We calculate resummed perturbative predictions for gaps-between-jets processes and compare to HERA data. Our calculation of this non-global observable needs to include the effects of primary gluon emission (global logarithms) and secondary gluon emission (non-global logarithms) to be correct at the leading logarithm (LL) level. We include primary emission by calculating anomalous dimension matrices for the geometry of the specific event definitions and estimate the effect of non-global logarithms in the large Nc limit. The resulting predictions for energy flow observables are consistent with experimental data.
