Infrared fixed point in SU(2) gauge theory with adjoint fermions

We apply Schrodinger-functional techniques to the SU(2) lattice gauge theory with N-f = 2 flavors of fermions in the adjoint representation. Our use of hypercubic smearing enables us to work at stronger couplings than did previous studies, before encountering a critical point and a bulk phase boundary. Measurement of the running coupling constant gives evidence of an infrared fixed point g(*) where 1/g(*)(2) = 0.20(4)(3).Lambda t the fixed point, we find a mass anomalous dimension gamma(m)(g(*)) = 0.31(6).
