CHARGED HADRON COMPOSITION OF THE FINAL-STATE IN E+E- ANNIHILATION AT HIGH-ENERGIES

Abstract:

The inclusive production of π± and K± mesons and of protons and antiprotons in e+e- annihilation has been measured at c.m. energies of W=14, 22 and 34GeV. Using time of flight measurements and Cerenkov counters the full momentum range has been covered. Differential cross sections and total particle yields are given. At particle momenta of 0.4 GeV/c more than 90% of the charged hadrons are pions. With increasing momentum the fraction of pions among the charged hadrons decreases. At W=34 GeV an...
