Title: Precision Measurement of Charged Pion and Kaon Differential Cross Sections in e⁺e⁻ Annihilation at √s=10.52 GeV

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⁻→qq¯ events, where q={u,d,s,c}. We present charge-integrated differential cross sections dσ /dz for h ±={π ±,K ±} as a function of the relative hadron energy z=2E h/√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>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.
