Single-Inclusive Hadron Production in Electron-Positron Annihilation at Next-to-Next-to-Next-to-Leading Order in QCD
Author(s): Chuan-Qi He, Hongxi Xing, Tong-Zhi Yang, and Hua Xing Zhu
Single-inclusive hadron production in electron-positron annihilation (SIA) represents the cleanest process for investigating the dynamics of parton hadronization, as encapsulated in parton fragmentation functions. In this Letter, we present, for the first time, the analytical computation of quantum … [Phys. Rev. Lett. 135, 101901] Published Tue Sep 02, 2025
