Constraints used in the UT fit

Before the B-Factory era, the fit was done using the measurements of UT sides (through semileptonic decays and mixing processes of the B mesons) and the determination of direct CP violation in Kaon system ( $\varepsilon_K$ ). Click on the plots for details.

$|V_{ub}/V_{cb}|$ $\varepsilon_K$ $\Delta m_d$ $\Delta m_d / \Delta m_s$

New determinations of UT angles and sides are now available, thanks to the results coming from the B-Factory experiments.

$\sin{2\beta}$ $\cos{2\beta}$ $\alpha$ $\gamma$ $2\beta+\gamma$ $B\rightarrow \tau\nu$

Constraints not yet used in the UT fit

Further 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.

$K\rightarrow \pi \nu \bar{\nu}$ $(B\rightarrow \rho/\omega \gamma)/(B\rightarrow K^* \gamma)$
