论文摘要
在彩色玻璃冷凝水框架中以近代领先的订单准确性计算,在高能量下,在高能量的深度非弹性散射中独家产生横向极化的重型媒介介子。除了与强耦合常数$α_s$成比例的第一个QCD校正外,我们还系统地包括第一个相对论校正与重夸克速度平方成正比的$ v^2 $。当与我们先前发表的纵向载体介子生产的结果结合到近临界订单的准确性时,这些结果使重型载体中生产的现象学计算以$ \ MATHCAL {O}(α_Sv^0,α_sv^0,α_s^0 v^2)$成为可能。当应用于HERA和LHC上的$ \ Mathrm {J}/ψ$和$购$生产时,找到了近代领先的订单计算与实验数据之间的良好协议。此外,我们证明,当提取Balitsky-Kovchegov进化方程的非扰动初始条件时,与结构函数分析相比,媒介中的产生可以提供其他约束。
Exclusive production of transversely polarized heavy vector mesons in deep inelastic scattering at high energy is calculated at next-to-leading order accuracy in the Color Glass Condensate framework. In addition to the first QCD correction proportional to the strong coupling constant $α_s$, we systematically also include the first relativistic correction proportional to the heavy quark velocity squared $v^2$. When combined with our previously published results for longitudinal vector meson production at next-to-leading order accuracy, these results make phenomenological calculations of heavy vector meson production possible at the order $\mathcal{O}(α_s v^0, α_s^0 v^2)$. When applied to $\mathrm{J}/ψ$ and $Υ$ production at HERA and at the LHC, a good agreement between the next-to-leading order calculations and experimental data is found. Additionally, we demonstrate that vector meson production can provide additional constraints compared to structure function analyses when the nonperturbative initial condition for the Balitsky-Kovchegov evolution equation is extracted.
