Inclusive. pi. /sup 0/ production by e/sup +/e/sup -/ annihilation at 34. 6 GeV center of mass energy

Abstract

The cross section for the process e/sup +/e/sup -/->..pi../sup 0/ + anything has been measured at an average Center of mass energy of 34.6 GeV for ..pi../sup 0/ energies between 0.7 and 17 GeV. The angular distribution for ..pi../sup 0/ energies larger than 2 GeV is of the form dsigma/d..cap omega..propor to1 + A cos/sup 2/theta, with A = 1.2+-0.5. The ratio of ..pi../sup 0/ to ..pi../sup +-/ production in the measured energy range is 2sigma(..pi../sup 0/)/(sigma(..pi../sup +/)+sigma(..pi../sup -/)) = 1.13+-0.18. The form of the differential cross sections agrees within the errors. The mean ..pi../sup 0/ multiplicity is 5.8+-0.9.
