摘要
本文介绍了在强子-强子双喷注产生中一些新事件形状和喷注率的定义。它们的设计旨在能够在 Tevatron 和 LHC 上实际测量，并且是全局的，以便可以使用当前可用的技术进行求和。我们解释了如何改变它们对束流碎裂的敏感性，限制其对纯微扰研究的影响，或者有意增强它以便专注于非微扰效应。给出了使用 CAESAR 获得的显式次领头对数求和结果。

33 pages, 14 figures, JHEP class included. Other results obtained with CAESAR are available at http://qcd-caesar.org. v2 includes extra references and clarifications in the discussions of prior work, as well as additional analytical information in the tables of properties of observables. v3 corrects figures 9 and 13 so as to correspond to cuts described in the text, corrects a misprint in caption of figure 10 and has improved versions of figures 5,7,8,10
