Query: Constraining conformal field theory with higher spin symmetry in four
  dimensions   We analyze the constraints on the general form and the singularity structure
of the correlation functions of the symmetric, traceless and conserved
stress-energy tensor implied by conformal invariance and higher spin symmetry
in four dimensions. In particular, we show that all these correlation functions
will have at most double pole singularities. We then compute the 4-, 5- and
6-point functions of the stress-energy tensor and find that they are linear
combinations of the three free field expressions (scalar, fermion and Maxwell
field). This is a strong indication that all such theories are essentially
free.
