JE T ffl e + e! qμq PITHYA events with fixed energy and fixed initial parton direction. ffl Four flavours u; d; c and b, five energies (,, 0, 0, 0 GeV) per parton 00 events of each. ffl Heavy mesons and fi -lepton decays made by PITHYA. ffl No any cuts at the PITHYA level. ffl Every initial (for GEANT) particle was separated in two hemispheres in q and μq momentum directions. ffl Only one part of e + e event was used as one of GEANT input event. ffl Magnetic field in the detector 3 Tesla, so for energy collection all calorimeter was used (no cuts in hemispheres). ffl There was no any spatial or cluster reconstruction procedure used sampling weighted energy sum ONLY. ffl Suggestions are: very good jet cluster finding and jet reconstruction procedures. ffl There were runs with separate particles as : e; fl; ß ; p; n; K 0 L, that are the jet components (,, 3,,, 0, 0, 0 GeV; 00 events of each) Vasiliy Morgunov Padova, - May 00
