Description

Title:
Global Analyses of Collinear Fragmentation Functions by the NPC

Abstract:

Fragmentation functions (FFs) are crucial non-perturbative ingredients in QCD for predicting hadron production cross sections in high-energy scattering processes. In this talk, I will present recent progress on global fits of FFs carried out by the Non-Perturbative Physics Collaboration (NPC). Our analyses incorporate a comprehensive set of precision measurements from the LHC, electron-positron collisions, and semi-inclusive deep inelastic scattering. Results will be shown for both light charged and neutral hadrons, highlighting the improved constraints on FFs achieved through these global fits. In addition, I will discuss applications of the framework developed in our work to parton distribution functions (PDFs).

Brief introduction about the speaker:

Dr. XiaoMin Shen is an associate researcher at the Institute of Modern Physics (IMP), Chinese Academy of Sciences. He earned his B.Sc. and Ph.D. from Zhejiang University (2020). Subsequently, he worked as postdoctoral researcher at Shanghai Jiao Tong University and later at Deutsches Elektronen-Synchrotron (DESY), before joining IMP in 2024. His research focuses on perturbative QCD and collider phenomenology, with recent emphasis on global analyses of fragmentation functions and parton distribution functions.
