A renormalisation group derivation of the overlap formulation
Nigel Cundy
Starting from the continuum Dirac operator, I construct a renormalisation group blocking which transforms the continuum action into a lattice action, and I specifically consider th…
Non-perturbative improvement of stout-smeared three flavour clover fermions
N. Cundy, M. Göckeler, R. Horsley +11
We discuss a 3-flavour lattice QCD action with clover improvement in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links fo…
Nucleon structure in terms of OPE with non-perturbative Wilson coefficients
W. Bietenholz, N. Cundy, M. Gockeler +7
Lattice calculations could boost our understanding of Deep Inelastic Scattering by evaluating moments of the Nucleon Structure Functions. To this end we study the product of electr…
New solutions to the Ginsparg-Wilson equation
Nigel Cundy
The overlap operator is just the simplest of a class of Dirac operators with an exact chiral symmetry. I demonstrate how a general class of chiral Dirac operators can be constructe…
