Inclusive γ and π0 production cross sections and energy fractions ine+e− annihilation at 29 GeV

Inclusive production cross sections for photons and p⁰'s ine⁺e^- annihilation at a center of mass energy of 29 GeV have been measured. The p⁰ production spectrum agrees with a corresponding measurement for p^±. The ratio of the p⁰ inclusive rate to the average for p^± is 0.92±0.14. The fractions of the total energy carried by photons and p⁰'s are 0.244±0.016 and 0.217±0.033, respectively. The fraction of total energy carried by all stable hadrons, prompt leptons and photons is determined to be 0.938±0.045, leaving 0.062±0.045 for neutrinos.
