Baryonic thermal screening mass at NLO
Leonardo Giusti, M. Laine, Davide Laudicina +2
We determine the resummed 1-loop correction to a baryonic thermal screening mass. The calculation is carried out in the framework of a dimensionally reduced effective theory, where…
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…
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…
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…
