Perturbative calculation of the clover term for Wilson fermions in any representation of the gauge group SU(N)
@article{Musberg2013PerturbativeCO, title={Perturbative calculation of the clover term for Wilson fermions in any representation of the gauge group SU(N)}, author={S. Musberg and Gernot M{\"u}nster and Stefano Piemonte}, journal={Journal of High Energy Physics}, year={2013}, volume={2013}, pages={1-6} }
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.
