   Chiral perturbation theory, dispersion relations and final state interactions in K -> pi pi

   Gilberto Colangelo🇨🇭

   We discuss the recent literature on the treatment of final state interactions in K -> pi pi. Various approaches are compared and particular emphasis is given to the possibility of combining dispersive methods with lattice input. Recent results on the dependence of various quantities on the quark masses at order p^6 in the chiral expansion are presented and the relevance for the lattice calculations is discussed.

   We present preliminary results of matrix elements of four-fermion operators relevant to the determination of e and e'/e using staggered fermions.

   The strong coupling constant from lattice QCD with N_f=2 dynamical quarks

   We compute ${\Lambda }_{\overline{MS}}$ for two flavors of light dynamical quarks using non-perturbatively $O(a)$ improved Wilson fermions. We improve on a recent calculation by employing Padé-improved two-loop and three-loop perturbation theory to convert the lattice numbers to the $\overline{MS}$ scheme.
