论文摘要
事件形状是确定强耦合和研究电子 - 峰值歼灭中强发效应的经典工具。在分析研究的背景下，强调校正采取了对横截面的贡献贡献的形式，可以从Borel尊重的分布的扰动歧义中提取。我们提出了一个简化的版本，即良好的穿着Gluon指数（DGE）的方法，我们称之为Eikonal DGE（Edge），该方法通过惊人的基本计算来确定所有主导功率校正对事件形状的校正。我们认为，我们的方法可以推广到与LHC物理学相关性的辐射事件形状和喷气形状。
Event shapes are classical tools for the determination of the strong coupling and for the study of hadronization effects in electron-positron annihilation. In the context of analytical studies, hadronization corrections take the form of power-suppressed contributions to the cross-section, which can be extracted from the perturbative ambiguity of Borel-resummed distributions. We propose a simplified version of the well-established method of Dressed Gluon Exponentiation (DGE), which we call Eikonal DGE (EDGE), which determines all dominant power corrections to event shapes by means of strikingly elementary calculations. We believe our method can be generalized to hadronic event shapes and jet shapes of relevance for LHC physics.
