Abstract
We present preliminary results of the running of the coupling in SU(2) gauge theory with 6 mass- less fundamental representation fermion flavors. We measure the coupling using the gradient flow method with Schrödinger functional boundary conditions. The results are consistent with perturbation theory in the weak coupling and we see an indication of infrared fixed point at strong coupling.
