利用非相对论量子色动力学(NRQCD)分解方法研究了未来的环形正负电子对撞机(CEPC)上的光生过程。包括直接和解决光子的贡献,我们提出了不同的分布的生产。我们的研究结果表明,将有相当多的事件,这意味着可以进行良好的测量的光产生,以进一步研究重夸克偶素物理在正负电子对撞机,除了强子对撞机。这一补充研究对于澄清重夸克偶素产生机制的现状是非常重要的。
Inclusive photoproduction at the future Circular-Electron-Positron-Collider (CEPC) is studied, using the non-relativistic quantum chromodynamics (NRQCD) factorization formalism. Including the contributions from both direct and resolved photons, we present different distributions for the production. Our results suggest that there will be considerable events, implying that well measurements of the photoproduction can be performed to further study heavy quarkonium physics at electron-positron colliders, in addition to hadron colliders. This supplemental study is very important for clarifying the current situation regarding the heavy quarkonium production mechanism.
