Towards mixed QCDxEW corrections to the charged-current Drell-Yan process with leptonic decay at high transverse masses

Abstract

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.
