What is CKMfitter ?
The CKMfitter package is a tool for a global CKM matrix analysis, offering the choice between many statistical approaches:
  • the Rfit (Range-fit) method, our frequentist approach described in details in the note below.
  • the ERfit (Extended Range-fit) method (see the note below also).
  • the 95% CL Scan method, the other frequentist approach from the BaBar Physics Book.
  • a Bayesian approach.
    • Graphical results are displayed in several two and one dimensional representations (such as the rho-eta plane), and numerical results are given for all the relevant CKM parameterizations, CKM elements, Standard Model predictions of rare K and B mesons decays, and theoretical parameters.

    The CKMfitter package is writen in FORTRAN for older modules and in C++ for recent developments. It is driven by data-cards where running options and input parameters are specified.
