"Table 2" of "Measurement of dijet production with a veto on additional central jet activity in pp collisions at sqrt(s)=7 TeV using the ATLAS detector"

The Gap Fraction as a function of the mean transverse momentum of the boundary jets for boundary jets having a rapidity difference in the range [2,3], using a jet veto Q0 = 20 GeV. Data are shown for two dijet selections: (i) the dijet system is defined as the two leading-pT jets in the event (ii) the dijet system is defined as the most forward-backward jets in the event.

针对快度差处于区间[2,3]内的边界喷注（boundary jets），采用喷注否决（jet veto）阈值Q0=20 GeV，给出间隙分数（Gap Fraction）随边界喷注平均横动量（mean transverse momentum）的变化关系。本数据集呈现了两种双喷注（dijet）选择方案的结果：(i) 双喷注系统定义为事件中横动量（transverse momentum，缩写pT）最高的两个喷注；(ii) 双喷注系统定义为事件中最前向与最反向的喷注。
