Stability of lattice QCD simulations and the thermodynamic limit
L. Del Debbio, L. Giusti, M. Lüscher +2
We study the spectral gap of the Wilson--Dirac operator in two-flavour lattice QCD as a function of the lattice spacing , the space-time volume and the current-quark mass $m…
Four quark operators in maximally twisted Wilson LQCD
Roberto Frezzotti, Giancarlo Rossi
We discuss how the peculiar properties of maximally twisted Wilson fermions can be exploited to set up a consistent LQCD computational scheme in which the CP-conserving matrix elem…
Non-perturbative renormalization of left-left four-fermion operators in quenched lattice QCD
M. Guagnelli, J. Heitger, C. Pena +2
We define a family of Schroedinger Functional renormalization schemes for the four-quark multiplicatively renormalizable operators of the and effective weak Hamil…
Reducing cutoff effects in maximally twisted lattice QCD close to the chiral limit
R. Frezzotti, G. Martinelli, M. Papinutto +1
When analyzed in terms of the Symanzik expansion, lattice correlators of multi-local (gauge-invariant) operators with non-trivial continuum limit exhibit in maximally twisted latti…
