Welcome

The CKMfitter package provides:

  • A global analysis of measurements determining the CKM matrix parameters in the framework of the Standard Model and its extensions.
  • A statistical treatment with various approaches, such as Frequentist (Rfit - the primary method used in the CKMfitter analyses) and Bayesian statistics.
  • Graphical and numerical constraints on CKM matrix elements, predictions on rare K and B meson decays, theoretical parameters, etc.
  • A userfriendly environment on the basis of program driving datacards.

Below we give examples for most recent plots and results obtained using CKMfitter in Rfit mode. More figures and tables, updated for each major change in the inputs, are found on the Plots and Results page.
