论文摘要

我们使用各种分数 - 能量定义对成对的成对的成对亲腐和kaons的生产横截面进行了新的测量。使用了两个不同的分数 - 能源定义，并将其与前面报道的常规分数 - 能量定义进行了比较。新的变量旨在以单人物碎片函数来识别二脑横截面，或者提供一种表征碎片过程中产生的横向动量的方法。在其他最近的Belle出版物中使用的有关轻型 - 火体生产横截面的其他Belle出版物中使用的更新的初始状态辐射校正获得了结果。此外，还使用此初始状态辐射校正对单个带电亲，kaons和质子的生产横截面进行了更新。横截面是从$ 558 \，{\ rm fb}^{ - 1} $数据样本在$υ（4S）$ resonance收集的kekb insmemmetric-enerygy $ e^+ e^+ e^ - $ Collider上收集的数据样本。

We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy definitions were used and compared to the conventional fractional-energy definition reported previously. The new variables aim at either identifying dihadron cross sections in terms of single-hadron fragmentation functions, or to provide a means of characterizing the transverse momentum created in the fragmentation process. The results were obtained applying the updated initial-state radiation correction used in other recent Belle publications on light-hadron production cross sections. In addition, production cross sections of single charged pions, kaons, and protons were also updated using this initial-state radiation correction. The cross sections are obtained from a $558\,{\rm fb}^{-1}$ data sample collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider.
