Duration: 15'+5'
We present a global analysis of Beauty, Top, Z, and Drell-Yan measurements within the framework of the Standard Model effective field theory (SMEFT). We use the minimal flavor violation (MFV) assumption and perform a combined analysis of up to 14 Wilson coefficients. We demonstrate that the combination of measurements from different sectors yields stronger constraints on the SMEFT coefficients than the individual fits and emphasize how synergies in the global approach allow probing scales as high as 18 TeV. Based on the constraints on the Wilson coefficients obtained in our analysis, we predict the dineutrino branching ratios ${\cal{B}}(B^0 \to K^{* 0} \nu \bar\nu)$ and ${\cal{B}}(B^+ \to K^+ \nu \bar\nu)$ and discuss how future measurements of these observables could provide new information in the search for physics beyond the Standard Model when being included in the global fit.
