Abstract

Abstract The hadronic energy produced in high-energy electron-positron annihilation has an angular correlation which can be computed by the asymptotically free perturbation theory of quantum chromodynamics. In finite orders, the correlation is not well behaved as the detectors become anti-collinear. We have calculated the leading behaviour to fourth order and conjecture an exponential expression for the sum of all orders. This expression obeys a non-trivial sum rule which lends support for its validity.
