A lattice approach to QCD in the chiral regime
Michele Della Morte, Roberto Frezzotti, Jochen Heitger
Non-perturbative lattice studies of QCD in the chiral thermodynamic regime, where chiral symmetry is spontaneously broken, require to deal with almost quark zero modes in a theoret…
Dynamical suppression of large instantons
Gernot Münster, Christel Kamp
We investigate the distribution of instanton sizes in the framework of a simplified model for ensembles of instantons. This model takes into account the non-diluteness of instanton…
The supersymmetric Ward identities on the lattice
F. Farchioni, A. Feo, T. Galla +5
Supersymmetric (SUSY) Ward identities are considered for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (gluinos). They are used in order to c…
The Schroedinger functional coupling in quenched QCD at low energies
Jochen Heitger, Hubert Simma, Rainer Sommer +1
Existing non-perturbative computations of the running coupling of quenched QCD in the Schroedinger functional scheme are extended to scales mu lying much deeper in the low-energy r…
Quenched twisted mass QCD at small quark masses and in large volume
M. Della Morte, R. Frezzotti, J. Heitger
As a test of quenched lattice twisted mass QCD, we compute the non-perturbatively O() improved pseudoscalar and vector meson masses and the pseudoscalar decay constant down to $…
SUSY Ward identities in 1-loop perturbation theory
Federico Farchioni, Alessandra Feo, Tobias Galla +6
We present preliminary results of a study of the supersymmetric (SUSY) Ward identities (WIs) for the N=1 SU(2) SUSY Yang-Mills theory in the context of one-loop lattice perturbatio…
