RESUMEN
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated tools in this field, the SMEFT-Tools 2022 workshop was held at the University of Zurich from 14th-16th September 2022. The current document collects and summarizes the content of this workshop.
RESUMEN
The anomalies in rare B decays endure. We present results of an updated global analysis that takes into account the latest experimental input - in particular the recent results on R K and BR ( B s â µ + µ - ) - and that qualitatively improves the treatment of theory uncertainties. Fit results are presented for the Wilson coefficients of four-fermion contact interactions. We find that muon specific Wilson coefficients C 9 ≃ - 0.73 or C 9 = - C 10 ≃ - 0.39 continue to give an excellent description of the data. If only theoretically clean observables are considered, muon specific C 10 ≃ 0.60 or C 9 = - C 10 ≃ - 0.35 improve over the Standard Model by Δ χ 2 ≃ 4.7 σ and Δ χ 2 ≃ 4.6 σ , respectively. In various new physics scenarios we provide predictions for lepton flavor universality observables and CP asymmetries that can be tested with more data. We update our previous combination of ATLAS, CMS, and LHCb data on BR ( B s â µ + µ - ) and BR ( B 0 â µ + µ - ) taking into account the full two-dimensional non-Gaussian experimental likelihoods.
