TL;DR: In this article, the energy dependence of the relative production rate of three-jet events is studied in hadronic e+e− annihilation events at center of mass energies between 22 and 46.7 GeV.

TL;DR: In this article, the authors compared 2nd-order QCD calculations with 3-and 4-jet models in the energy range of 14.0-46.7 GeV and showed that the observed excess of spherical events can partially be explained by the production of multi-parton events expected from higher order QCD contributions.

TL;DR: In this paper, the authors investigated the inclusion of D∗± mesons in single tagged photon-photon collisions using the JADE detector at PETRA, and reconstructed the mesons through their decay into D0+π± where the D0 decays via D0→Kππ0.

TL;DR: In this paper, the JADE detector at PETRA has been analyzed in terms of the semi-muonic branching ratios and fragmentation functions of heavy quarks, and the results show that the expected softening effect in the fragmentation due mainly to gluon emission can be observed.
