"Table 11" of "Measurements of the differential jet cross section as a function of the jet mass in dijet events from proton-proton collisions at $\sqrt{s} =$ 13 TeV"

Measurements of the differential jet cross section are presented as a functionof jet mass in dijet events, in bins of jet transverse momentum, with and withouta jet grooming algorithm. The data have been recorded by the CMS Collaborationin proton-proton collisions at the LHC at a center-of-mass energy of 13\TeV andcorrespond to an integrated luminosity of 2.3\fbinv. The absolute cross sections show slightly different jettransverse momentum spectra in data and Monte Carlo event generatorsfor the settings used. Removing this transverse momentum dependence,the normalized cross section for ungroomed jets is consistent with theprediction from Monte Carlo event generators for masses below 30\% ofthe transverse momentum. The normalized cross section for groomed jetsis measured with higher precision than the ungroomed crosssection. Semi-analytical calculations of the jet mass beyond leadinglogarithmic accuracy are compared to data, as well as predictions atleading order and next-to-leading order, which include partonshowering and hadronization. Overall, in the normalized cross section,the theoretical predictions agree with the measured cross sectionswithin the uncertainties for masses from 10 to 30\% of the jettransverse momentum.

本数据集报道了双喷注事件中，以喷注横向动量为分箱依据、分别采用喷注修整算法与未采用该算法时，以喷注质量为变量的微分喷注截面测量结果。所用数据由CMS合作组于大型强子对撞机（Large Hadron Collider, LHC）的13TeV质心系能量质子-质子碰撞中采集，对应积分亮度为2.3 fb⁻¹。在所用参数设置下，绝对截面在实验数据与蒙特卡洛事件产生器的模拟结果中展现出略有差异的喷注横向动量谱。去除该横向动量依赖后，未修整喷注的归一化截面在喷注质量低于其横向动量30%的范围内，与蒙特卡洛事件产生器的预言结果一致。修整后喷注的归一化截面测量精度高于未修整喷注的截面。将超越领头对数精度的喷注质量半解析计算结果，以及包含部分子簇射与强子化过程的领头阶、次领头阶理论预言，与实验数据进行了对比。整体而言，在归一化截面中，当喷注质量为其横向动量的10%至30%区间内，各理论预言与测量截面在不确定度范围内相符。
