I discuss the extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements under the Standard Model (SM) framework from a global fit combining observables that satisfy the double requirement of being precisely known both experimentally and theoretically. The analysis shown here relies on the CKMfitter package, consisting of a frequentist approach that employs the Range fit (Rfit) scheme to handle theoretical uncertainties.

Discussion (0). Continue with ORCID to comment.

  1. A common origin of the Higgs boson and the flavor hierarchies

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A unified TeV-scale model produces the Higgs as a pseudo-Goldstone boson from the same gauge deconstruction that suppresses light-family Yukawa couplings and CKM mixing while leaving PMNS mixing anarchic.

  2. 2024 Update on $\varepsilon_K$ with lattice QCD inputs

    hep-lat 2024-12 conditional novelty 4.0 of 10

    Using 2024 inputs and exclusive |V_cb|, the standard model predicts only about 65% of the measured |epsilon_K|, a gap that vanishes when inclusive |V_cb| is used.
