We present a study of inclusive pi0 and eta production in e+e- annihilation at sqrt(s)=(approx) 10 GeV. Our analysis is based on integrated luminosities of 46.2 pb-1 taken at the Y(1S) resonance and 42.1 pb-1 taken in the neighboring continuum. We measure the inclusive pi0 and eta spectra for direct Y(1S) -> 3 g decays and continuum processes e+ e- -> q qbar and obtain the following mean particle multiplicities per event: Continuum:<n(pi0)>=3.64+-0.21+-0.36, <n(eta)>=0.22+-0.04+-0.03Y(1S) -> 3g:<n(pi0)>=3.39+-0.14+-0.34, <n(eta)>=0.35+-0.04+-0.04We compare our results with predictions of different fragmentation models and with other measurements performed in e+e- annihilation at similar center-of-mass energies.

Abstract
We present a study of inclusive pi0 and eta production in e+e- annihilation at sqrt(s)=(approx) 10 GeV. Our analysis is based on integrated luminosities of 46.2 pb-1 taken at the Y(1S) resonance and 42.1 pb-1 taken in the neighboring continuum. We measure the inclusive pi0 and eta spectra for direct Y(1S) -> 3 g decays and continuum processes e+ e- -> q qbar and obtain the following mean particle multiplicities per event: Continuum:
