A strategy to study the role of the charm quark in explaining the Delta{I}=1/2 rule
L. Giusti, P. Hernandez, M. Laine +2
We present a strategy designed to separate several possible origins of the well-known enhancement of the Delta{I}=1/2 amplitude in non-leptonic kaon decays. In particular, we seek…

Low-energy couplings of QCD from topological zero-mode wave functions
L. Giusti, P. Hernandez, M. Laine +2
By matching 1/m^2 divergences in finite-volume two-point correlation functions of the scalar or pseudoscalar densities with those obtained in chiral perturbation theory, we derive…
