摘要

我们在3.0中实现了一个新的接口，支持所有具有完全轻子最终态的二色子和摩擦子过程，从而实现次领先阶(NLO)+部子阵雨（PS）匹配计算。为了证明它的能力，我们使用erwig 7.3研究了pp→e+νeμ−ν¯μγ+X摩擦子产生过程中的部分子阵雨效应，NLO QCD振幅为3.0。我们估计了尺度变化的不确定性，并分析了发电水平削减对部分淋浴事件的影响。这项研究展示了新界面的潜力，并提供了对多玻色子产生过程中固定阶计算和部分子淋浴效应之间相互作用的见解，这对于精确测量至关重要，并且超出了大型强子对撞机和未来对撞机的标准模型搜索。2025年由美国物理学会出版

NLO QCD parton shower matching for pp→e+νeμ−ν¯μγ+X

We present the implementation of a new interface in 3.0 supporting all diboson and triboson processes with fully leptonic final states, enabling next-to-leading order (NLO)+parton shower (PS) matched calculations. To demonstrate its capabilities, we study parton shower effects in the triboson production process pp→e+νeμ−ν¯μγ+X using erwig 7.3 with NLO QCD amplitudes from 3.0. We estimate uncertainties from scale variations and analyze the impact of generation-level cuts on parton shower events. This study showcases the new interface’s potential and provides insights into the interplay between fixed-order calculations and parton shower effects in multiboson production processes, crucial for precision measurements and beyond the Standard Model searches at the LHC and future colliders.
