Interjet Energy Flow/Event Shape Correlations
Abstract
We identify a class of perturbatively computable measures of interjet energy flow, which can be associated with welldefined color flow at short distances. As an illustration, we calculate correlations between event shapes and the flow of energy, Q_{ω}, into an interjet angular region, ω, in highenergy twojet e^{+}e^{}annihilation events. Laplace transforms with respect to the event shapes suppress states with radiation at intermediate energy scales, so that we may compute systematically logarithms of interjet energy flow. This method provides a set of predictions on energy radiated between jets, as a function of event shape and of the choice of the region ω in which the energy is measured. Nonglobal logarithms appear as corrections. We apply our method to a continuous class of event shapes.
