The CKMfitter group provides:
- A global analysis of measurements determining the CKM matrix parameters in the framework of the Standard Model and some of its extensions.
- Graphical and numerical constraints on CKM matrix elements, predictions on rare K and B meson decays, theoretical parameters, etc.
- The statistical treatment is based on Frequentist statistics and Rfit (Range fit) for the theoretical uncertainties.
