Charged hadron production in e/sup +/e/sup -/ annihilation at. sqrt. s = 29 GeV

We have used data from the Time Projection Chamber at the SLAC storage ring PEP to study the inclusive production of charged hadrons in e/sup /+//e/sup /-// annihilation at a center of mass energy of 29 GeV. Charged particles were identified by simultaneous dEdx and momentum measurements. We present cross sections and particle fractions for ..pi../sup/plus minus//, k/sup + -/, and p(/ovr/p//) as a function of energy, momentum, rapidity, and transverse momentum. We compare the predictions of various hadronization models to the data and note discrepancies at high momentum.
