Revisiting relativistic corrections to inclusive production at B factories: Complete expansion for three-body quarkonium production
Sheng-Juan Jiang, Sai Cui, Guang-Zhi Xu +1
We revisit the calculations of relativistic corrections to inclusive production at B factories. For quark-level subprocesses with three-body final states, we carry out a ful…

Order- relativistic corrections to heavy-quark fragmentation into -wave quarkonium states
Sai Cui, Sheng-Juan Jiang, Guang-Zhi Xu +1
Within the framework of nonrelativistic QCD (NRQCD) factorization,and based on the Collins--Soper operator definition of fragmentation functions, we present a systematic calculatio…

Study on Toponium: Spectrum and Associated Processes
Sheng-Juan Jiang, Bai-Qing Li, Guang-Zhi Xu +1
In this paper, we calculate the toponium spectrum in the potential model with the screened effects. Coulombic part is dominant for toponium, and the coefficient of the Coulomb pote…
