Abstract:	摘要： 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 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>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. 出版者： United States: American Physical Society 出版日期： 2013-08-06 出處： Physical review letters, 2013-08, Vol.111 (6), Article 062002 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.111.062002
