Description

Abstract:

Doubly heavy hadrons contain two heavy quark components, their production involves both perturbative and nonperturbative aspects of QCD. They provide an ideal laboratory to study QCD. On the one hand, the research on the production mechanism of doubly heavy hadrons can test the existing theories (such as perturbative QCD, nonrelativistic QCD, etc.), on the other hand, it can help us search for the doubly heavy hadron states that have not been observed in experiments. In this talk, I will introduce our recent progress in the production of doubly heavy hadrons, including the production of doubly heavy hadrons at the electron-positron colliders and the precision calculation of fragmentation functions for the production of doubly heavy mesons.
