A bstractWe calculate the Sheikholeslami-Wohlert coefficient of the O(a) improvement-term for Wilson fermions in any representation of the gauge group SU(N) perturbatively at the one-loop level. The result applies to QCD with adjoint quarks and to $ \mathcal{N} $ = 1 supersymmetric Yang-Mills theory on the lattice. 

Non-perturbative O(a) improvement of the SU(3) sextet model

Improved results for the mass spectrum of N = 1 supersymmetric SU(3) Yang-Mills theory

This talk summarizes the results of the DESY-Munster collaboration for N = 1 supersymmetric Yang-Mills theory with the gauge group SU(3). It is an updated status report with respect to our

Spectroscopy of four-dimensional N = 1 supersymmetric SU(3) Yang-Mills theory

Supersymmetric gauge theories are an important building block for extensions of the standard model. As a first step towards Super-QCD we investigate the pure gauge sector with gluons and gluinos on

Ward identities in N = 1 supersymmetric SU(3) Yang-Mills theory on the lattice

The introduction of a space-time lattice as a regulator of field theories breaks symmetries associated with continuous space-time, i.e. Poincare invariance and supersymmetry. A non-zero gluino mass

Numerical Results for the Lightest Bound States in N=1 Supersymmetric SU(3) Yang-Mills Theory.

This work determines the masses of the lightest bound states in SU(3) N=1 SYM theory and shows the formation of a supermultiplet of bound states, which provides a clear evidence for unbroken supersymmetry.

We present a lattice study of the SU (4) gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial

Nonperturbative renormalization of the supercurrent in $\mathcal{N} = 1$ Supersymmetric Yang-Mills Theory
