We perform a global fit, by discussing the relevance of the mixing in the first generation. We use for the first time in this context a Montecarlo analysis to extract the confidence intervals and correlations between observables. Our results show that machine learning, made jointly with the SHAP values, constitute a suitable strategy to use in this kind of analysis.42 p.application/pdfengcc-by (c) Alda, J. et al., 2022https://creativecommons.org/licenses/by/4.0/Fenomenologia (Física)Física de partículesEquacions de LagrangePhenomenological theory (Physics)Particle physicsLagrange equationsinfo:eu-repo/semantics/article7242672022-10-05info:eu-repo/semantics/openAccess
