Weak low-energy couplings from topological zero-mode wavefunctions

P. Hernandez, M. Laine, C. Pena +3

We discuss a new method to determine the low-energy couplings of the $Δ S = 1$ weak Hamiltonian in the $ε$ -regime. It relies on a matching of the topological poles in $1/ m^{2}$ of three…

A numerical treatment of Neuberger's lattice Dirac operator

P. Hernandez, K. Jansen, L. Lellouch

We describe in some detail our numerical treatment of Neuberger's lattice Dirac operator as implemented in a practical application. We discuss the improvements we have found to acc…

Two-Cutoff Lattice Regularization of Chiral Gauge Theories

P. Hernandez

I review our method to formulate chiral gauge theories on the lattice based on a two-cutoff lattice regularization, and discuss recent numerical results in a chiral U(1) gauge theo…
