Spectrum of SU(2) SUSY Yang-Mills Theory with a light gluino

R. Peetz, F. Farchioni, C. Gebert +1

We report on new results for the low lying spectrum of N=1 SUSY Yang-Mills Theory with SU(2) as the gauge group. Simulating on larger lattices at κ= 0.194 and β= 2.3, we slowly app…

Lattice supersymmetric Ward identities

F. Farchioni, A. Feo, T. Galla +5

SUSY Ward identities for the N=1 SU(2) SUSY Yang-Mills theory are studied on the lattice in a non-perturbative numerical approach. As a result a determination of the subtracted glu…

SUSY Ward identities in N=1 SYM theory on the lattice

F. Farchioni, A. Feo, T. Galla +5

The SUSY Ward identities (WIs) for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (gluinos) are considered. The study is performed in the fram…

Effects of Topology in the Dirac Spectrum of Staggered Fermions

F. Farchioni, I. Hip, C. B. Lang

We compare the lower edge spectral fluctuations of the staggered lattice Dirac operator for the Schwinger model with the predictions of chiral Random Matrix Theory (chRMT). We veri…

Instanton classical solutions of SU(3) fixed point actions on open lattices

F. Farchioni, A. Papa

We construct instanton-like classical solutions of the fixed point action of a suitable renormalization group transformation for the SU(3) lattice gauge theory. The problem of the…

The fixed point action for the Schwinger model: a perturbative approach

F. Farchioni, V. Laliena

We compute the fixed point action of a properly defined renormalization group transformation for the Schwinger model through an expansion in the gauge field. It is local, with coup…
