Testing chiral effective theory with quenched lattice QCD
L. Giusti, P. Hernandez, S. Necco +3
We investigate two-point correlation functions of left-handed currents computed in quenched lattice QCD with the Neuberger-Dirac operator. We consider two lattice spacings a~0.09,0…
Determination of the weak Hamiltonian in the SU(4) chiral limit through topological zero-mode wave functions
P. Hernandez, M. Laine, C. Pena +3
A new method to determine the low-energy couplings of the weak Hamiltonian is presented. It relies on a matching of the topological poles in of three-point correlato…
Non-perturbative renormalisation of left-left four-fermion operators with Neuberger fermions
P. Dimopoulos, L. Giusti, P. Hernandez +5
We outline a general strategy for the non-perturbative renormalisation of composite operators in discretisations based on Neuberger fermions, via a matching to results obtained wit…
Probing the chiral weak Hamiltonian at finite volumes
P. Hernandez, M. Laine
Non-leptonic kaon decays are often described through an effective chiral weak Hamiltonian, whose couplings ("low-energy constants") encode all non-perturbative QCD physics. It has…
On the determination of low-energy constants for transitions
L. Giusti, P. Hernandez, M. Laine +3
We present our preliminary results for three-point correlation functions involving the operators entering the effective Hamiltonian with an active charm quark, obtained us…
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…
