We assess the impact of Renormalisation Group Equations (RGEs) in global SMEFT fits, incorporating QCD, electroweak, and Yukawa corrections. By assigning characteristic energy scales to LEP and LHC cross-sections, we quantify RGE effects on current and projected fits at the HL-LHC and FCC-ee. Additionally, we evaluate the role of RGEs in the sensitivity of these colliders to UV models matched...

We discuss a novel open-source Python package, jelli: a JAX-based EFT likelihood, which provides an easy-to-use and highly efficient framework particularly suited to global SMEFT/WET analyses and the phenomenology of heavy new physics models. The nature of the tool is generic, allowing a differentiable high-dimensional likelihood to be constructed from any set of observables and measurements...

SMEFT global analyses commonly encounter two major challenges:
1. An incomplete set of observables.
2. Ad-hoc flavour assumptions.
These issues significantly undermine the reliability and applicability of the results.In this talk, I propose the CLEW framework for a complete global analysis free of flavour assumptions. By integrating both high- and low-energy data, our framework is able...
