Abstract

Inclusive momentum spectra are measured for all charged particles and for each of π^±, K^±, K⁰/K⁰, and p/p in hadronic events produced via e⁺e^- annihilation at √(s)=58GeV . The measured spectra are compared with QCD predictions based on the modified leading log approximation(MLLA). The MLLA model reproduces the measured spectra well. The energy dependence of the peak positions of the spectra is studied by comparing the measurements with those at other energies. The energy dependence is also well described by the MLLA model.
