Description
Electroweak (EW) corrections, significantly influenced by Sudakov logarithms, become the predominant higher-order effect at the TeV scale and beyond. In this study, we compute EW corrections in the high-energy limit for selected dimension-six SMEFT operators. Our findings reveal that while four-fermion operators exhibit universally similar corrections as those seen in the Standard Model (SM), distinct structural variations emerge for other operators. We investigate the phenomenological implications of these findings through illustrative processes involving four-fermion operators and assess the impact of Sudakov EW corrections on the tails of differential distributions, both at the LHC and future lepton colliders. Given the complex effects of EW corrections within SMEFT, we caution against the use of simplistic K-factor approaches, which do not adequately capture the nuanced physics involved.
