论文摘要
LHC在LHC处的Hadronic喷气机的患病率要求对射流形成和结构有深入的了解，以达到实验和理论精确度的最高水平。在LHC和以前的山脉中，有许多测量了JET子结构，但是目标可观察物将各种起源的物理效应混合在一起。基于最新的提议，该信件使用139 fb $^{ - 1} $ $ \ sqrt {s} = 13 $ \ sqrt {s} $ tev Proton-proton-proton-Proton碰撞数据对Lund Jet Plane进行了双分化横截面测量，该$ \ sqrt {s} = 13 $ \ sqrt {s} = 13 $ \ sqrt { - 1} $。该测量使用带电的颗粒实现细胞分辨率，并得到接受和检测器效应的校正。将几种Parton淋浴蒙特卡洛模型与数据进行了比较。没有发现单个模型与整个平面上的测量数据一致。
The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many measurements of jet substructure at the LHC and previous colliders, but the targeted observables mix physical effects from various origins. Based on a recent proposal to factorize physical effects, this Letter presents a double-differential cross-section measurement of the Lund jet plane using 139 fb$^{-1}$ of $\sqrt{s}=13$ TeV proton-proton collision data collected with the ATLAS detector using jets with transverse momentum above 675 GeV. The measurement uses charged particles to achieve a fine angular resolution and is corrected for acceptance and detector effects. Several parton shower Monte Carlo models are compared with the data. No single model is found to be in agreement with the measured data across the entire plane.
