The 4d one component lattice model in the broken phase revisited
Janos Balog, Anthony Duncan, Ray Willey +2
Measurements of various physical quantities in the symmetry broken phase of the one component lattice with standard action, are shown to be consistent with the critical beh…
Correlation functions at small quark masses with overlap fermions
L. Giusti, P. Hernandez, M. Laine +4
We report on recent work on the determination of low-energy constants describing Delta{S}=1 weak transitions, in order to investigate the origins of the Delta{I}=1/2 rule. We focus…
Structure functions of the 2d O(n) non-linear sigma models
Janos Balog, Peter Weisz
We investigate structure functions in the 2-dimensional (asymptotically free) non-linear O(n) sigma-models using the non-perturbative S-matrix bootstrap program. In particular the…
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…
String excitation energies in SU(N) gauge theories beyond the free-string approximation
Martin Lüscher, Peter Weisz
In the presence of a static quark--antiquark pair, the spectrum of the low-lying states in SU() gauge theories is discrete and likely to be described, at large quark separations…
Structure functions of 2d integrable asymptotically free models
Janos Balog, Peter Weisz
We investigate structure functions in the 2--dimensional (asymptotically free) non--linear O--models using the non--perturbative S--matrix bootstrap program. In particular t…
