Abstract: (APS)

We propose a simple alternative to the sphericity as a measure of jet structure in e+e− annihilation. Our variable has the property that it can be reliably calculated in perturbation theory in quantum chromodynamics (QCD) for large Q2. It is not sensitive to the details of quark and gluon decay into color-singlet hadrons. We discuss the nonperturbative effects which are important at moderate Q2.
