论文摘要
在本文中，我们调查了$ \ cos2d $ azimuthal的不对称性，以$ e〜p \ rightArrow e〜j/ψ〜JET〜X $，其中$ j/ψ$ -JET对几乎在横向飞机中几乎背对背，在广义零件模型（GPM）的框架内。我们使用非相关性QCD（NRQCD）来计算$ J/ψ$生产幅度，并将颜色单元（CS）和Color Octet（CO）贡献对不对称性进行贡献。我们使用运动学中的Gluon TMD的不同参数估算了不对称性，这些参数可以在未来的电子离子对撞机（EIC）上访问，还研究了横向动量依赖（TMD）进化对不对称性的影响。我们介绍了来自不同状态的NRQCD中不同状态的贡献。
In this article, we investigate the $\cos2ϕ_t$ azimuthal asymmetry in $e ~p\rightarrow e ~J/ψ~Jet~ X$, where the $J/ψ$-jet pair is almost back-to-back in the transverse plane, within the framework of the generalized parton model(GPM). We use non-relativistic QCD(NRQCD) to calculate the $J/ψ$ production amplitude and incorporate both color singlet(CS) and color octet(CO) contributions to the asymmetry. We estimate the asymmetry using different parameterizations of the gluon TMDs in the kinematics that can be accessed at the future electron-ion collider (EIC) and also investigate the impact of transverse momentum dependent (TMD) evolution on the asymmetry. We present the contributions coming from different states to the asymmetry in NRQCD.
