Abstract
We look for UV fixed points of non-abelian gauge theories in dimensions with Dirac fermions in the fundamental representation, using the available five-loop -function and employing Pad\'e-Borel resummation techniques and Pad\'e approximants to the series expansion in . We find evidence for a UV-fixed point for theories with . We also compute the anomalous dimensions and of respectively the fermion mass bilinear and the gauge kinetic term operator at the UV fixed point.
