"Table 4" of "Measurement of the ratio of differential cross sections {\sigma}(ppbar -> Z + b jet)/{\sigma}(ppbar -> Z + jet) in ppbar collisions at sqrt(s)=1.96 TeV"

Fermilab-Tevatron. Measurement of the ratios of cross section for B-JET to JET production in association with a Z0 boson in antiproton-proton interactions at a centre of mass energy of 1.96 TeV. The data, with an integrated luminosity of 9.7 fb-1, is presented as functions of the jet and Z0 transverse momentum, the jet pseudorapidity and the azimuthal angle between the Z0 and the closest jet. Events must have at least one jet with jets being reconstructed from energy deposits in the calorimeter using an iterative mid-point cone algorithm with delta R = 0.5. Events are rejected if the missing ET is > 60 GeV to reduce t-tbar contamination.

本数据集收录费米实验室-万亿电子伏特加速器（Fermilab-Tevatron）实验中，质心系能量为1.96 TeV的反质子-质子对撞过程里，伴随Z0玻色子（Z0 boson）产生的B喷流（B-JET）与喷流（JET）的产生截面比测量结果。该数据集的积分亮度为9.7 fb⁻¹，其物理分布以喷流与Z0玻色子的横向动量、喷流的赝快度（pseudorapidity），以及Z0与最近喷流之间的方位角作为变量进行呈现。对撞事件需至少包含一个喷流，所有喷流均通过ΔR=0.5的迭代中点锥算法（iterative mid-point cone algorithm）对量能器中的能量沉积进行重建得到。为抑制顶夸克对（t-tbar）本底污染，需剔除缺失横向动量（missing ET）大于60 GeV的事件。
