In the context of quark (as for lepton) mixing, we introduce the concept of the matrix of unitarity triangle angles $\Phi$, emphasising that it carries equivalent information to the complex mixing matrix $V$ itself. The angle matrix $\Phi$…

We obtain new upper and lower bounds on the number of unit perimeter triangles spanned by points in the plane. We also establish improved bounds in the special case where the point set is a section of the integer grid.
We describe the present status of the Unitarity Triangle and we give an outlook for its future determinations. We discuss new sets of fundamental flavour parameters and comment briefly on new physics beyond the Standard Model.
We show that the angle $\alpha_{ds}$ of the ``flattest'' unitarity triange can be directly measured using the decays $\overline{B}_{d}\to \phi \overline{K}^{(*)0}$ and $\overline{B}_{s}\to \phi{K}^{(*)0}$. Using both $\overline{B}_{d}$ and…

The current results on B to pipi decays and SU2 constraints on the Unitarity Triangle angle alpha or phi_2 from the B-factories are summarised. Based on these measurements, predictions of the isospin analysis constraints at the end of the…

Overconstraining the CKM unitarity triangle with precision measurements of its angles continues to test the validity of the Standard Model. One of these angles, gamma/phi_3, has been measured by studying B+- -> D K+- decays, where D = D0 or…
The precision of the neutrino oscillation parameters measurements has improved and will continue to improve as the next-generation experiments become online. Beyond the more precise measurements of the mixing angles and phases used to…
I review several methods for determining the CKM phases $\alpha \equiv \phi_2$ and $\gamma \equiv \phi_3$ through CP asymmetry measurements in hadronic B decays. The current status of these measurements and the near future feasibility of…
