Abstract: (arXiv)
The goal of this study is to investigate the scaling behaviour of our 2 HEX action. For this purpose, we compute the Nf=3N_f=3 spectrum and compare the results to our 6 EXP action. We find a large scaling window up to 0.15fm\sim 0.15\,\mathrm{fm} along with small scaling corrections at the 2%-level and full compatibility with our previous study. As a second important observable to be tested for scaling, we chose the non-perturbatively renormalized quenched strange quark mass. Here we find a fairly flat scaling with a broad scaling range up to 0.15fm\simeq 0.15\,\mathrm{fm} and perfect agreement with the literature.
