Abstract
We present a study of inclusive π0 and {eng} production in e+e- annihilation at {Mathematical expression}. Our analysis is based on integrated luminosities of 46.2 pb-1 taken at the υ (1 S) resonance and 42.1 pb-1 taken in the neighboring continuum. We measure the inclusive π0 and {eng} spectra for direct υ (1 S) → 3 g decays and continuum processes {Mathematical expression} and obtain the following mean particle multiplicities per event: {Mathematical expression} We compare our results with predictions of different fragmentation models and with other measurements performed in e+e- annihilation at similar center-of-mass energies.
