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…
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…
Topological susceptibility in full QCD with Ginsparg-Wilson fermions
L. Giusti, G. C. Rossi, M. Testa
We show that, if the formula for the topological charge density operator suggested by fermions obeying the Ginsparg-Wilson relation is employed, it is possible to give a precise an…
Numerical Exploration of the RI/MOM Scheme Gauge Dependence
L. Giusti, S. Petrarca, B. Taglienti +1
The gauge dependence of some fermion bilinear RI/MOM renormalization constants is studied by comparing data which have been gauge-fixed in two different realizations of the Landau…
A Study of the 't Hooft Model with the Overlap Dirac Operator
F. Berruto, L. Giusti, C. Hoelbling +1
We present the results of an exploratory numerical study of two dimensional QCD with overlap fermions. We have performed extensive simulations for U(N_c) and SU(N_c) color groups w…
Quenched Results for Light Quark Physics with Overlap Fermions
L. Giusti, C. Hoelbling, C. Rebbi
We present results of a quenched QCD simulation with overlap fermions on a lattice of volume V = 16^3X32 at beta=6.0, which corresponds approximatively to a lattice cutoff of 2 GeV…
