Running coupling in SU(2) with adjoint fermions    [PDF]

Jarno Rantaharju, Kari Rummukainen, Kimmo Tuominen

We present a measurement of the Schr\"odinger Functional running coupling in SU(2) lattice gauge theory with adjoint fermions. We use HEX smearing and clover improvement to reduce the discretization effects. We obtain a robust continuum limit for the step scaling, which confirms the existence of a non-trivial fixed point.
