论文摘要
我们在非相关QCD（NRQCD）分解形式上的框架中，计算到独家过程$γ+γ\ to J/ψ+J/ψ$的独家过程$γ+γ\ to J/ψ+J/ψ$的次要领先顺序（QCD）校正。评估了SuperkekB电子峰值对撞机以及未来山脉的横截面，例如圆形电子正电子对撞机（CEPC）和国际线性撞机（ILC）。数值结果表明，希望在未来十年内由Belle II检测器看到该过程。
We calculate the next-to-leading order (NLO) quantum chromodynamics (QCD) correction to the exclusive process $γ+γ\to J/ψ+J/ψ$ in the framework of non-relativistic QCD (NRQCD) factorization formalism. The cross sections at the SuperKEKB electron-positron collider, as well as at the future colliders, like the Circular Electron Positron Collider (CEPC) and the International Linear Collider (ILC), are evaluated. Numerical result indicates that the process will be hopefully to be seen by the Belle II detector within the next decade.
