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…
Rare Radiative Decays of Z boson into S- and P-wave Charmonium within the Bethe-Salpeter Model
Asif Ali, Yi-Jie Li, Guang-Zhi Xu +1
We employ the Bethe-Salpeter (BS) model to investigate radiative decays of the Z boson into charmonium. Within the instantaneous approximation of the BS equation, we analyze the re…
Exclusive process production in ultraperipheral proton and nuclear collisions at the HL-LHC and FCC
Meng-Kun Jia, Xiao-Bo Jin, Kui-Yong Liu +1
We present a next-to-leading-order (NLO) analysis of exclusive production via photon-photon fusion in ultraperipheral collisions at the High-Luminosity Large Hadron Colli…
Rare Exclusive Decays of the Z-boson into S-wave Quarkonia within the Bethe-Salpeter Formalism
Asif Ali, Yi-Jie Li, Guang-Zhi Xu +1
This paper investigates the rare decays of the Z boson into S-wave quarkonia within the Bethe-Salpeter formalism. Both the production of double S-wave quarkonia and radiative decay…
Associated Production of Charmonia-Bottomonia with Color-Octet Channels at the Z Factory, CEPC and FCC-ee
Xiao-Peng Wang, Yi-Jie Li, Guang-Zhi Xu +1
Within the nonrelativistic QCD (NRQCD) framework, we investigate the associated production of charmonia+bottomonia at future super factory and at the CEPC/FCC-ee. The color-oct…
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…
