摘要：

In a comparison of the jet measures sphericity, spherocity and thrust we find that the spherocity axis exhibits strong instabilities against small changes of particle directions and points in many cases in the direction of a single particle rather than describing the events as a whole. Sphericity does not allow the unique association of particles with jets. Thrust yields such an association and can easily be computed in a non-iterative way. We generalize the concept of thrust for application to triple-jets and present a non-iterative procedure for computing the three axes as well as a scalar quantity measuring the three-jet structure of individual events. © 1979, Springer-Verlag.
