AI 中文摘要
Drell-Yan过程是大型强子对撞机的关键精确基准，也是标准模型（SM）和标准模型有效场论（SMEFT）效应的灵敏探针。充分利用未来大型强子对撞机数据需要达到百分之几水平的SM预测，这促使人们进行精确的电弱（EW）和混合QCD×EW修正。本文报告了在嵌套软共线减法框架内对高横向质量下带电流Drell-Yan轻子衰变的混合QCD×EW修正计算的进展。在给出NLO验证后，展示了NNLO真实修正的结果，并比较了它们在中性流和新开发的带电流通道中的影响。这些贡献对于匹配大型强子对撞机当前和未来测量精度至关重要，特别是在电弱效应因Sudakov对数增强的区域。
英文摘要
The Drell-Yan process is a key precision benchmark at the Large Hadron Collider and a sensitive probe of SM and SMEFT effects. Fully exploiting future LHC data requires percent-level SM predictions, motivating precise EW and mixed QCDxEW corrections. In this proceeding we report of the progress towards the calculation of mixed QCDxEW corrections to charged-current Drell-Yan with leptonic decay at high transverse masses, performed within the Nested Soft-Collinear Subtraction framework. After presenting a validation at NLO, we show results for the NNLO real corrections and compare their impact in the neutral-current and newly developed charged-current channels. These contributions are essential to match the current and future precision of LHC measurements, especially in regions where electroweak effects are enhanced by Sudakov logarithms.
