LHC物理学的精确QEDXQCD恢复理论：现状与更新
Precision QEDXQCD Resummation Theory for LHC Physics: Status and Update
摘要：
我们介绍了IR改进的DGLAP-CS理论的基本内容，它涉及到新的MC友好的指数化方案，用于精确计算LHC物理的高阶修正，其中QED和QCD的IR奇异性在严格的簇射/ME匹配的存在下同时被取消到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。如所预期的，IR改进的簇射重新填充对于标准HERWIG6.5输入参数的能量分数z的较低值和伴随的p_T的较低值。可能的现象学影响进行了讨论。
英文摘要：
We present the elements of the IR-improved DGLAP-CS theory as it relates to the 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 alpha and in alpha_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. As expected, the IR-improved shower re-populates lower values of the energy fraction z and lower values of the attendant p_T for the standard HERWIG6.5 input parameters. Possible phenomenological implications are discussed.
