论文摘要
基于非同性QCD框架，我们研究了HERA，EIC和LHEC的半包含深度无弹性电子普罗替型散射（SIDIS）的$υ$生产，其主要目的是评估三个碰撞者在三个胶合器中观察$∂$ dodroduction的可行性。发现颜色贡献（CO）贡献对综合和差分截面具有至关重要的影响，从而进一步确定了CO机制的重要性。通过将运动学切割设置为$ p_ {考虑到其缺乏测量的$υ$电源。但是，在相同的切割条件下，EIC和LHEC可以分别累积约8.7美元\ times10^{2} $和$ 3.7 \ times10^{4} $在一年中重建$υ$事件，这显然表明了检测到$∂$ qured sidis processes the twoter compy $ ep的前景。
Based on the nonrelativistic QCD framework, we study the $Υ$ production in semi-inclusive deep inelastic electron-proton scattering (SIDIS) at HERA, EIC, and LHeC, with the main aim of assessing the viability of observing $Υ$ electroproduction at the three colliders. The color-octet (CO) contributions are found to have a crucial effect on both the integrated and differential cross sections, serving to further establish the significance of the CO mechanism. By setting the kinematic cuts to $p_{t,Υ}^{\star 2}>1~\textrm{GeV}^{2}$, $W>50$ GeV, $2<Q^2<100~\textrm{GeV}^2$, and $0.3<z<0.9$, only a few electroproduced $Υ$ events can be generated at HERA, partially accounting for its lack of measured $Υ$ electroproduction. However, under the same cut conditions, the EIC and LHeC can accumulate about $8.7\times10^{2}$ and $3.7\times10^{4}$ reconstructed $Υ$ events in one operation year, respectively, which manifestly indicates the prospect of detecting the $Υ$-related SIDIS processes at the two forthcoming $ep(eA)$ colliders.
