Reanalysis reduces uncertainties in fragmentation functions
Data from PETRA and LEP show consistent fragmentation patterns
Abstract
We present studies of the angular and momentum distributions of charged particles in hadronic final states of e+e- annihilation. Some results are derived from reanalysis of data of the JADE experiment operating at the PETRA e+e- collider at DESY from 1979 to 1986 while other data are from OPAL.
