Abstract

In this talk, we present our recent work about QCD evolution effect on the transverse momentum dependent(TMD) observables for collins asymmetries in e+e- annihilation to di-hadron and semi-inclusive deep inelastic scattering(SIDIS) processes, by taking into account TMD evolution effect is studied under CSS formalism. Our result shows the evolution effect will bring a significant correction to TMD distributions extracted form experiment data.

Summary

Introduction

Transverse momentum dependent(TMD) pardon distributions have always been a hot topic for both experiment and theory sides in recent years. We present our recent work about QCD evolution effect on the transverse momentum dependent(TMD) observables for collins asymmetries in e+e− annihilation to di-hadron and semi-inclusive deep inelastic scattering(SIDIS) processes, by taking into account TMD evolution effect is studied under CSS formalism. Our result shows the evolution effect will bring a significant correction to TMD distributions extracted form experiment data.
