Description
After more than a decade of operations, the LHC is entering into a new era of precision physics. This evolution demands the refinement of our tools to uncover New Physics (NP), leveraging the statistical advantages of unprecedented data volume. Assuming NP lies beyond the current energy reach, the Standard Model Effective Field Theory (SMEFT) emerges as a powerful framework for an indirect discovery program. SMEFT enables a minimal, model-independent extension of the SM, providing a consistent and systematic parameterization of modified interactions. In this talk, I will present our latest efforts to constrain these interactions using a global and comprehensive analysis of current data, while exploring the potential of future collider experiments. I will emphasize the critical importance of theoretical precision, focusing on the role of renormalization group evolution (RGE) in ensuring consistency across datasets spanning multiple energy scales. Finally, I will highlight the intricate interplay between SMEFT parameters and parton distribution functions (PDFs). As PDFs are extracted from datasets overlapping with SMEFT analyses, an inconsistent treatment risks absorbing NP effects into the proton’s structure.
