  After some introductory comments on the peculiar features of slowly running
theories, I will report results obtained using the Schrodinger functional
technique for two gauge theories that are believed to lie near the bottom of
the conformal window: the SU(3) theory with two adjoint Dirac fermions, and the
SU(4) theory with six Dirac fermions in the two-index antisymmetric
representation. In both cases we find a small beta function in strong coupling,
but we cannot confirm or rule out an infrared fixed point. In both theories the
mass anomalous dimension levels off, staying well below 0.5, much like the
theories with fermions in the two-index symmetric representation investigated
earlier.
