description: Measurements of inclusive differential cross sections for charged pion and kaon production in e+e- annihilation have been carried out at a center-of-mass energy of √s=10.52 GeV. The measurements were performed with the Belle detector at the KEKB e+e- collider using a data sample containing 113×106 e+e -→qq̄ events, where q={u,d,s,c}. We present charge-integrated differential cross sections dσh±/dz for h±={π±,K±} as a function of the relative hadron energy z=2Eh/√s from 0.2 to 0.98. The combined statistical and systematic uncertainties for π± (K±) are 4% (4%) at z∼0.6 and 15% (24%) at z∼0.9. The cross sections are the first measurements of the z dependence of pion and kaon production for z&gt;0.7 as well as the first precision cross section measurements at a center-of-mass energy far below the Z0 resonance used by the experiments at LEP and SLC.
