论文摘要
由于QCD的非线性结构在SMALL-X时，较高的碰撞能量最终可能导致标准固定阶扰动理论和线性演变的伪造。严格基于准确的喷射测量值的新物理学研究无疑将通过观察到这种观察结果，即通过角射流去相关性，考虑到Mueller-Navelet Jets。作为边境山脉之一，FCC-EP通过不对称碰撞对Parton密度具有很大的观察潜力。我们旨在测试方位角射流去相关的可观察性与最近的事件发生器（Herwig，Pythia）在FCC-EP中心的粒子水平上的质量能量中心3.5 TEV在质子电子碰撞中3.5 TEV。喷气机由抗KT算法（r = 0.5）重建，$ p_ {t}> 35 GEV $，并在| y | <6的范围内选择。相关的速度区域已经通过速度分类（$ΔY$）的Mueller-Navelet喷气机（$Δφ$）之间的相对角度差异（$π-Δφ$）分析。
Higher collision energies at future colliders may eventually lead to the falsification of standard fixed-order perturbation theory and linear evolutions due to non-linear structure of QCD at small-x. New physics researches that is strictly based on accurate jet measurements will undoubtedly have this observation known as BFKL effect via angular jet decorrelations taking into account the Mueller-Navelet jets. As one of the frontier colliders, FCC-ep, has a great observation potential on parton densities through asymmetrical collisions. We aim to test the observability of azimuthal angular jet decorrelations with the recent event generators (HERWIG, PYTHIA) at the particle level for FCC-ep centre of mass energies 3.5 TeV in proton-electron collisions. Jets are reconstructed by the Anti-kT algorithm (R = 0.5), with $p_{T} > 35 GeV$ and selected in the range of |y|<6. Relevant rapidity regions has been analyzed with the azimuthal-angle difference between Mueller-Navelet Jets ($ΔΦ$) in the rapidity seperation ($Δy $) and the distributions of cosn($π-ΔΦ$) are presented in comparison as the result.
