As is briefly mentioned in Other dimensions, extensions, and generalisations there is an option to introduce infinitely many additional coupling constants that enter via phase factor θ θ ( x ) = θ θ 0 + θ θ 2 x 2 + . . . . As was noted, the second such coefficient θ θ 2 will affect five-point AdS/CFT correlation functions, but not the three-point ones, which seems to be in tension with the results obtained directly from imposing higher spin symmetry on the correlation functions. Later, it was shown that the terms in the equations that result from θ θ 2 , 4 , . . . are too non-local and lead to an infinite result for the AdS/CFT correlation functions.
