Azimuthal Correlations ine+e−Jets: A Test of Quantum Chromodynamics

Abstract

In $e^{+}{e}^{-}\to \mathrm{hadrons}$ an azimuthal angular correlation between a plane defined by the hadrons and the plane formed by the beams and the jet axis is possible. In the naive parton model the correlation vanishes. In quantum chromodynamics it does not and with reasonable assumptions may be reliably calculated in perturbation theory for large center-of-mass energy. We calculate it in lowest nontrivial order and discuss its physical origins and experimental observation.
