Inclusive. pi. sup + , K sup + and p, p production in e sup + e sup minus annihilation at radical s = 29 GeV
Measurements of {pi}{sup {plus minus}}, K{sup {plus minus}} and p, {bar p} inclusive cross sections and fractions in e{sup +}e{sup {minus}} annihilation at {radical}s = 29 GeV are presented. The momentum interval covered corresponds to 0.01 < z < 0.90, where z = p/p{sub beam}. The analysis is based on approximately 70 pb{sup {minus}1} of data collected between 1984 and 1986 with the TPC/2{gamma} detector at PEP. Charged particles are identified by a simultaneous measurement of momentum and ionization energy loss (dE/dx). The recently upgraded detector's momentum resolution of ({Delta} p/p){sup 2} = (1.5%){sup 2} + (0.65% p (GeV/c)){sup 2} and a dE/dx resolution of typically 3.5% allow the measurements to be extended to higher z than previously reported.
