TL;DR: Hadron jets produced in e+e− annihilation between 13 GeV and 31.6 GeV in c.m. energy at PETRA are analyzed in this article, showing that the broadening of the jets is not uniform in azimuthal angle around the quark direction but tends to yield planar events with large and growing transverse momenta in the plane and smaller transverse momentsa normal to the plane.
