测量了高助推对产生的顶夸克的微分截面作为顶夸克和系统运动学观测值的函数，使用质子-质子碰撞在质心能量为。该数据集对应于2015年和2016年在欧洲核子研究中心大型强子对撞机上使用ATLAS探测器记录的积分光度。事件与两个大半径射流在最终状态，一个与横向动量和第二，用于测量。顶夸克的候选人分离的多喷流背景下使用喷子结构信息和协会与标记的喷。测量的光谱校正探测器的影响，粒子级基准相空间和部分子级有限相空间，并比较几个Monte Carlo模拟通过calculatedvalues。在基准相空间区域中的生产横截面与理论预测进行比较。
Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark andsystem kinematic observables using proton-proton collisions at a center-of-mass energy of. The data set corresponds to an integrated luminosity of, recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Events with two large-radius jets in the final state, one with transverse momentumand a second with, are used for the measurement. The top-quark candidates are separated from the multijet background using jet substructure information and association with a-tagged jet. The measured spectra are corrected for detector effects to a particle-level fiducial phase space and a parton-level limited phase space, and are compared to several Monte Carlo simulations by means of calculatedvalues. The cross-section forproduction in the fiducial phase-space region is, to be compared to the theoretical prediction of.
