The most precise current determination of the Unitarity Triangle angle $\phi_3$ is presented. It is obtained using the decay $B^+ \to D^{(*)} K^+$, with Dalitz plot analysis of the subsequent $D \to K_S \pi^+\pi^-$ decay. The result is…

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 $\Phi$…
