Description

With clear signals of physics beyond the Standard Model proven to be elusive both at high- and low-energy searches, it has become imperative to relate experimental data of various scales in an accurate and to a large extent model-independent manner in order to corner even the smallest new physics signals. In this talk, I focus on observables that probe CP violation from the quark and lepton sector without requiring sources of flavour violation beyond the SM. Within the EFT of SMEFT I present a global analysis of EDMs and constraints from the LHC, highlighting correlations between high-energy and the high-intensity frontier as well as possible cancellations that cannot be captured without such a global approach. On a different note I discuss how precision flavour can test light NP and in particular how to search for the QCD axion at LHCb.
