Next-to-leading-order relativistic and QCD corrections to prompt $J / ψ$ pair photoproduction at future $e^{+} e^{-}$ colliders

Zhi-Guo He, Xiao-Bo Jin, Bernd A. Kniehl +1

Within the framework of nonrelativistic-QCD factorization, we calculate both the next-to-leading-order relativistic and QCD corrections to prompt $J / ψ$ pair production, with feeddo…

Relativistic corrections to prompt double charmonium hadroproduction near threshold

Zhi-Guo He, Xiao-Bo Jin, Bernd A. Kniehl

We calculate the relativistic corrections to prompt $J / ψ$ pair and $J / ψ + ψ (2 S)$ hadroproduction through the color-singlet channel within the framework of nonrelativistic QCD (NRQCD)…

Investigating the heavy quarkonium radiative transitions with the effective Lagrangian method

Zhi-Guo He

In this work, we study the radiative decay of heavy quarkonium states by using the effective Lagrangian approach. Firstly, we construct the spin-breaking terms in the effective Lag…
