摘要:

本文综述了基于IR改进的DGLAP-CS理论的LHC物理新方法的最新进展,它涉及到一种新的MC友好的指数化方案,用于LHC物理高阶修正的精确计算,其中QED和QCD的IR奇异性在严格的簇射/ME匹配下同时被消除到α和α s的所有阶。我们提出的第一个MC数据比较隐含的新阵雨本身与标准的使用HERWIG6.5 MC事件发生器作为测试用例在LHC能量。

英文摘要:

We summarize the recent progress in a new approach to precision LHC physics based on the IR-improved DGLAP-CS theory as it relates to a new MC friendly exponentiated scheme for precision calculation of higher order corrections to LHC physics in which IR singularities from both QED and QCD are canceled to all orders in αand in α_s simultaneously in the presence of rigorous shower/ME matching. We present the first MC data comparing the implied new showers themselves with the standard ones using the HERWIG6.5 MC event generator as a test case at LHC energies.
