Abstract
Recently it was shown that the scaling dimension of the operator in scale invariant theory may be computed semiclassically, and this was verified to leading order (two loops) in perturbation theory at leading and subleading . Here we extend this verification to six loops, once again at leading and subleading . We then perform a similar exercise for a theory with a multiplet of real scalars and an invariant hexic interaction. We also investigate the strong-coupling regime for this example.
