Cowan, G D

Measurements of ..pi../sup + -/, K/sup + -/ and p, anti p inclusive cross sections and fractions in e/sup +/e/sup -/ annihilation at ..sqrt..s = 29 GeV are presented. The momentum interval covered corresponds to 0.01 < z < 0.90, where z = pp/sub beam/. The analysis is based on approximately 70 pb/sup -1/ of data collected between 1984 and 1986 with the TPC2..gamma.. detector at PEP. Charged particles are identified by a simultaneous measurement of momentum and ionization energy loss (dEdx). The recently upgraded detector's momentum resolution of (..delta..pp)/sup 2/ = (1.5%)/sup 2/ + (0.65% . p (GeVc) )/sup 2/ and a dEdx resolution of typically 3.5% allow the measurements to be extended to higher z than previously reported. 70 refs., 59 figs., 7 tabs
