Abstract:The unitarity triangle can be determined by means of two measurements of its sides or angles. Assuming the same relative errors on the angles (α, β, γ) and the sides (R b , R t ), we find that the pairs (γ, β) and (γ, R b ) are most efficient in determining (¯ ,η) that describe the apex of the unitarity triangle. They are followed by (α, β), (α, R b ), (R t , β), (R t , R b ) and (R b , β). As the set |V us |, |V cb |, R t and β appears to be the best candidate for the fundamental set of flavour violating parameters in the coming years, we show various constraints on the CKM matrix in the (R t , β) plane. Using the best available input we determine the universal unitarity triangle for models with minimal flavour violation (MFV) and compare it with the one in the Standard Model. We present allowed ranges for sin 2β, sin 2α, γ, R b , R t and ∆M s within the Standard Model and MFV models. We also update the allowed range for the function F tt that parametrizes various MFV-models.

“…Lattice QCD provides the opportunity for evaluating these non-perturbative effects, and in table 1 (taken from ref. 3 ) I present a number of the most important examples. The factors in bold-type in the second column of table 1 are quantities which are frequently taken from lattice calculations.…”

I review two subjects in which lattice simulations are making, or can make in the future, a significant contribution to particle physics phenomenology. The first subject is the evaluation of quantities which enter into the determination of the vertex A of the unitarity triangle from experimental measurements of decay rates and mixing amplitudes. These quantities include the form-factors for semileptonic Bdecays, the leptonic decay constants of the B and Bs mesons and the B-parameters for B d -B d and Bs-Bs mixing and the corresponding parameter for K-K mixing, B K . In the second part of this talk I will review the status and prospects for the evaluation of K → ππ amplitudes and for the subsequent study of the ∆I = 1/2 rule and the evaluation of ε ′ /ε.

“…This is experimentally very challenging because of the rapid oscillations in the B 0 s − B0 s system. Nevertheless, the experimental lower bounds on M s / M d already yield interesting constraints on the b−d unitarity triangle [8].…”

We discuss neutral B s,d meson mixing and b-hadron lifetimes from the perspective of recent lattice calculations. In particular, we consider matrix elements which can be combined with measured ∆M s,d to constrain |V td |, the lifetime ratios τ (Λ b )/τ (B 0 d ) and τ (B − )/τ (B 0 d ) and the lifetime difference, ∆Γ Bs /Γ Bs , in the neutral B s meson system. ‡ Based on talks given by the authors in the UK Phenomenology Workshop on Heavy Flavours and CP Violation, 17th -22nd September 2000, Durham, England.
