Abstract We present a comprehensive global analysis of the dimension-six standard model effective field theory (SMEFT) including electroweak precision data, LEP2 fermion pair production and diboson measurements, LHC Drell–Yan production, Higgs-boson measurements, top-quark observables, and a set of flavour observables including F=2 Δ F = 2 and F=1 Δ F = 1 processes. The analysis is performed in a Bayesian setup within the open-source framework, floating simultaneously the relevant standard model (SM) parameters and (in the flavour sector) hadronic inputs together with the SMEFT Wilson coefficients. Leading-logarithmic renormalization-group evolution (RGE) is included from the UV matching scale down to the electroweak scale, as well as the matching to the low energy effective theory (LEFT) for flavour observables, with subsequent running to hadronic scales. Results are presented for two benchmark flavour-symmetric SMEFT scenarios, U (3) ⁵ U (3) 5 and U (2) ⁵ U (2) 5, and for representative UV scales = 3 Λ = 3 and 10~ TeV 10 TeV (with RGE), compared to a reference setup without RGE.
