摘要:

我们报道了新的测量结果的生产截面对带电π介子和K介子作为其分数能量的函数,使用各种分数能量的定义。使用了两种不同的分数能量定义,并与以前报道的传统分数能量定义进行了比较。新的变量的目的是在确定双强子截面的单强子碎裂功能,或提供一种手段,在碎裂过程中产生的横向动量的特点。结果得到应用更新的初始状态辐射校正中使用的其他最近贝尔出版物轻强子生产截面。此外,生产截面的单电荷π介子,K介子和质子也更新使用这种初始状态的辐射校正。截面是从$558\,{\rm fb}^{-1}$数据样本中获得的,该数据样本是在KEKB非对称能量$e^+ e^-$对撞机上用Belle探测器在$Υ(4S)$共振处收集的。

英文摘要:

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.
