Constraints used in the UT fit

Before the starting of B-Factory experiments, the fit was done using the measurements of sides (through semileptonic decays and mixing processes of the B mesons) and the determination of direct CP violation in Kaon system ().

Several new determinations of UT angles are now available, thanks to the results coming from the B-Factory experiments.

Constraints not yet used in the UT fit

New bounds are available from rare B and K decays. They do not still have a strong impact on the global fit and they are not used at present.
