Description of the Bayesian method The method is explained in detail in M. Ciuchini et al., JHEP 0107 (2001) 013, hep ph/0012308. Given N parameters x_{i}(A,~B_{K ...
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 ...
Constraint from \cos 2\beta There are two ways to access the value of %$\cos 2\beta$%, which allows one to remove the ambiguity between %$\beta$% and %$\pi \beta ...
Constraint from \sin 2\beta The mixing induced CP asymmetry in the %$B^0 \rightarrow J/\psi K^0$% decay allows one to determine the sine of the angle %$2\beta ...
Constraint from \Delta m_d /\Delta m_s The %$B^0_s \bar{B}^0_s$% oscillation frequency, which is related to the mass difference between the light and the heavy ...
Constraint from \Delta m_d In the Standard Model, %$B^0 \bar{B}^0$% oscillations occur through a second order process (a box diagram) with a loop containing W ...
Constraint from \varepsilon_K Indirect CP violation in the Kaon system is usually expressed in terms of %$ \varepsilon_K $% parameter which is the fraction of ...
Constraint from \left V_{ub} / V_{cb} \right B hadrons can decay through the %$b \rightarrow c$% and %$b \rightarrow u$% transitions. The relative ratio of ...
Input values for parameters and constraints entering in the UT fit. Most of the experimental averages are taken from HFAG. For the CKM angles we use the pdf's obtained ...
