“…From the overlapped region in (ρ,η) plane, I read ρ = 0.20 (12), (3.15) η = 0.37(07) (3.16) without the sin(2β ) constraint. Including the sin(2β ) constraint significantly improves the precision, givingρ Lat05 = 0.16 (7), (3.17) η Lat05 = 0.37(4), (3.18) which are consistent with the PDG values [19] ρ = 0.20 (9) and η = 0.33 (5), and the accuracy is comparable, as shown in Fig. 15.…”

A full determination of the CKM matrix using recent results from lattice QCD is presented. To extract the CKM matrix in a uniform fashion, I exclusively use results from unquenched lattice QCD as the theory input for nonperturvative QCD effects. All 9 CKM matrix elements and all 4 Wolfenstein parameters are obtained from results for gold-plated quantities, which include semileptonic decay form factors and leptonic decay constants of B, D and K mesons, and B 0 −B 0 and K 0 −K 0 mixing amplitudes.

“…The determination of the CKM matrix elements using lattice QCD has been discussed long time; see, e.g., Refs. [9,10] for recent reviews. A more detailed review on recent lattice calculations of K meson physics (such as the K 0 −K 0 mixing and K → πlν decay) can be found in Ref.…”

“…[42,43,23]. As for Mtm-LQCD with cloverimproved quark action, the promising quenched tests presented some years ago in [44] have been recently extended in [45] down to pion masses of 300 MeV or lower, confirming the absence of large cutoff effects.…”

In this review we discuss the general features of maximally twisted lattice QCD. In particular, we illustrate how automatic O(a) improvement can be achieved and how it is possible to set up a lattice regularization scheme where the problem of wrong chirality mixing (be it finite or infinite) affecting the computation of the matrix elements of the CP-conserving effective weak Hamiltonian is neatly avoided, while having at the same time a positive determinant even for non-degenerate quark pairs. The question of reducing the large cutoff effects that appear when the quark mass tends to zero as a consequence of parity and iso-spin breaking in the action is also addressed. It is shown that such dangerous lattice artifacts are strongly suppressed if the clover term is added to the action or, alternatively, the critical mass is chosen so as to enforce the restoration of parity.

Since the previous kaon conference in 2009, there has been very significant improvement in the precision which can be reached in lattice simulations for standard physical quantities, such as quark masses, the leptonic decay constants, B K and the form factors for K 3 decays. In this talk I focus on quantities which have not been previously computed in lattice computations and for which the RBC-UKQCD collaborations are developing the necessary theoretical and computational framework. There are rare-kaon decays and the long-distance contributions to the K L -K S mass splitting, ∆m K . For ∆m K exploratory numerical studies have been performed to test the techniques and to gain some understanding of the precision which might be reached. For rare kaon decay amplitudes the exploratory work is now beginning.
