"Figure 2b" of "Search for long-lived particles using out-of-time trackless jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

The distributions of the most impactful input variables to the TD jet tagger for signal (red, lighter) and collision background (blue, darker). They include the charged (upper left) and neutral (upper right) hadron energy fractions, the number of track constituents in the jet (middle left), the $\Delta R$ between the jet axis and the closest track associated with the PV (middle right), and the jet time (lower).

本数据集展示了TD喷流标记器（TD jet tagger）针对信号样本（红色，色调更浅）与碰撞本底（蓝色，色调更深）时，影响最为显著的输入变量的分布情况。这些变量包括：带电强子能量占比（左上）与中性强子能量占比（右上）、喷流内的径迹组成粒子数目（中左）、喷流轴与原顶点（Primary Vertex, PV）关联的最近径迹之间的ΔR值（中右），以及喷流时间（下方）。
