AI 中文摘要
我们对$ep$碰撞中排他性重夸克偶素电产生进行了各种唯象学研究，这些研究既与HERA的现有测量相关，也与即将到来的电子-离子对撞机（EIC）相关。我们在微扰QCD（pQCD）的次领头阶（NLO）下，为HERA可观测到的$J/\psi$电产生中的各种可观测量提供了定量预测，这些预测在光子虚度$Q^2$和$\gamma^* p$质心能量的广泛范围内可作为有价值的基准。随后，我们讨论了即将到来的EIC将如何补充现有测量，并最后主张需要为高$Q^2$下的$J/\psi$电产生建立一个专门且系统的重求和框架。
英文摘要
We perform various phenomenological studies of exclusive heavy-quarkonium electroproduction in $ep$ collisions that are relevant for both the existing measurements from HERA and the forthcoming Electron-Ion Collider (EIC). We provide quantitative predictions at next-to-leading order (NLO) in perturbative QCD (pQCD) for various observables accessible at HERA for $J/ψ$ electroproduction that serve as valuable benchmarks across a broad range of photon virtualities $Q^2$ and $γ^* p$ centre-of-mass energies. We then discuss how the forthcoming EIC will complement existing measurements and end by advocating the need for a dedicated and systematic resummation framework for $J/ψ$ electroproduction at large $Q^2$.
