提出了质子-反质子碰撞中质子能量中心的孤立瞬发光子的包容产生截面的测量。结果是使用费米实验室 Tevatron 的对撞机探测器收集的完整 Run II 数据样本获得的，该样本对应于积分光度。横截面被测量为光子横向能量的函数，在范围和赝快速区域中。将结果与 QCD 领先阶的部分顿簇蒙特卡罗模型以及次领先阶微扰 QCD 计算的预测进行比较。后者与测量的横截面表现出良好的一致性。
A measurement of the inclusive production cross section of isolated prompt photons in proton-antiproton collisions at center-of-mass energyis presented. The results are obtained using the full Run II data sample collected with the Collider Detector at the Fermilab Tevatron, which corresponds to an integrated luminosity of. The cross section is measured as a function of photon transverse energy,, in the rangeand in the pseudorapidity region. The results are compared with predictions from parton-shower Monte Carlo models at leading order in QCD and from next-to-leading-order perturbative QCD calculations. The latter show good agreement with the measured cross section.
