介绍了CMS中射流能量尺度的测量结果和2011年分析的射流能量校正情况。这些测量是用质子-质子碰撞中收集的数据样本进行的，其质量中心能量为7 TeV，对应的综合光度为4.9fb−1。使用Dijet和光子/Z+射流事件来测量CMS探测器中的射流能量响应。粒子流方法试图在射流聚类之前，基于所有相关子探测器的信息，分别重建事件中的每个粒子。
Measurements of the jet energy scale in CMS and the status of the jet energy corrections for 2011 analyses are presented. The measurements have been performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.9fb−1. Dijet and photon/Z+jets events are used to measure the jet energy response in the CMS detector. The results are presented for the Particle Flow approach, which attempts to reconstruct individually each particle in the event, prior to the jet clustering, based on information from all relevant subdetectors.
