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…

Order- corrections to heavy quark fragmentation to S-wave heavy quarkonium
Sai Cui, Yi-Jie Li, Guang-Zhi Xu +1
Within the framework of nonrelativistic quantum chromodynamics (NRQCD) factorization, we compute the relativistic corrections to the fragmentation of a heavy q…
