论文摘要
我们提出了从最终状态和初始状态与基于天线的Vincia Parton淋浴中的QCD演化相结合的算法。其中一种算法结合了与光子发射相关的完整软和共线结构，但在计算上可能昂贵，而另一个则以较低的成本近似软结构。包括Fermions和W Bosons的辐射，并建立了低于强化量表的光子辐射的策略。我们显示了淋浴算法在LHC处的淋浴算法和WW生产中的结果，显示了包含完整的软结构和辐射处理W玻色子的影响。
We present algorithms that interleave photon radiation from the final state and the initial state with the QCD evolution in the antenna-based Vincia parton shower. One of the algorithms incorporates the complete soft and collinear structure associated with photon emission, but may be computationally expensive, while the other approximates the soft structure at a lower cost. Radiation from fermions and W bosons is included, and a strategy for photon radiation off leptons below the hadronization scale is set up. We show results of the application of the shower algorithms to Drell-Yan and WW production at the LHC, showing the impact of the inclusion of the full soft structure and treatment of radiation off W bosons.
