论文摘要
我回顾了一些有关夸克碎片的选定主题，特别注意$ e^+e^ - $ nihihihitation中的底部和魅力 - 夸克的生产以及包含非扰动校正。特别是，我讨论了在扰动碎片函数框架中进行的计算的最新进展，以及将它们扩展到其他过程和更高准确性的观点。特别注意使用有效的强耦合常数来建模强发效应。
I review a few selected topics concerning heavy-quark fragmentation, taking particular care about bottom- and charm-quark production in $e^+e^-$ annihilation and the inclusion of non-perturbative corrections. In particular, I discuss recent developments of calculations carried out in the framework of perturbative fragmentation functions and the perspective to extend them to other processes and higher accuracy. Special attention is paid to the use of an effective strong coupling constant to model hadronization effects.
