Abstract
We discuss higher spin gauge symmetry breaking in AdS space
from a holographic perspective. Indeed, the AdS/CFT correspondence
implies that 
= 4 SYM theory at vanishing coupling constant
is dual to a theory in AdS which exhibits higher spin gauge symmetry
enhancement. When the SYM coupling is non-zero, the current
conservation condition becomes anomalous, and correspondingly the
local higher spin symmetry in the bulk gets spontaneously broken. In
agreement with previous results and holographic expectations, we
find that the Goldstone mode responsible for the symmetry breaking
in AdS has a non-vanishing mass even in the limit in which the gauge
symmetry is restored. Moreover, we show that the mass of the
Goldstone mode is exactly the one predicted by the
correspondence. Finally, we obtain the precise form of the higher
spin supercurrents in the SYM side.
