Query: Surprises from the Resolution of Operator Mixing in N = 4 SYM   We reexamine the problem of operator mixing in N = 4 SYM. Particular
attention is paid to the correct definition of composite gauge invariant local
operators, which is necessary for the computation of their anomalous dimensions
beyond lowest order. As an application we reconsider the case of operators with
naive dimension Delta_0=4, already studied in the literature. Stringent
constraints from the resummation of logarithms in power behaviours are
exploited and the role of the generalized N = 4 Konishi anomaly in the mixing
with operators involving fermions is discussed. A general method for the
explicit (numerical) resolution of the operator mixing and the computation of
anomalous dimensions is proposed. We then resolve the order g^2 mixing for the
15 (purely scalar) singlet operators of naive dimension \Delta_0=6. Rather
surprisingly we find one isolated operator which has a vanishing anomalous
dimension up to order g^4, belonging to an apparently long multiplet. We also
solve the order g^2 mixing for the 26 operators belonging to the representation
20' of SU(4). We find an operator with the same one-loop anomalous dimension as
the Konishi multiplet.
