论文摘要
基于非相关性量子染色体动力学分解框架，我们研究了未来高能$ e^+e^+E^ - $ collider，国际线性撞机（ILC）的包含$ J/ψ$光增生，其中初始光子来自激光和电子（PROSITRON）的后射击。中间状态， $ c \ bar {c} $$（{}^3 \！s_1^{[\ textbf {1}]} $，$ {}^1 \！s_0^{[\ textbf {8}]} $，$ {}^3 \！s_1^{[\ textbf {8}]} $，$ {}^3 \！并考虑了已解决的光生产过程。数值结果表明，ILC处的$ j/ψ$光生生产的横截面可能非常大，并且通过$ c \ bar {c}（{}^1 \！s_0^{[\ textbf {8}]}）通过$ c \ bar {c}（{}^1 \！我们还为$ j/ψ$光生效提供了各种运动学分布。结合碰撞的高光度，ILC处的$ j/ψ$光生生效应提供一个很好的平台来测试NRQCD分解。
Based on the non-relativistic quantum chromodynamics factorization framework, we study the inclusive $J/ψ$ photoproduction at the future high energy $e^+e^-$ collider, International Linear Collider(ILC), where the initial photons come from the back-scattering of laser and electron (positron). The intermediate states, $c\bar{c}$$({}^3\!S_1^{[\textbf{1}]}$,${}^1\!S_0^{[\textbf{8}]}$,${}^3\!S_1^{[\textbf{8}]}$,${}^3\!P_{0,1,2}^{[\textbf{8}]})$, and resolved photoproduction processes are considered. Numerical results show that the cross section of $J/ψ$ photoproduction at the ILC could be very large, and the single resolved process via $c\bar{c}({}^1\!S_0^{[\textbf{8}]})$ intermediate state dominates primarily the production. We also present various kinematic distributions for $J/ψ$ photoproduction. Combining the high luminosity of the collision, $J/ψ$ photoproduction at the ILC shall provide a good platform to test the NRQCD factorization.
