Towards Massless Higher Spin Extension of D = 5 , N = 8 Gauged Supergravity


The AdS5 superalgebra PSU(2, 2|4) has an infinite dimensional extension, which we denote by hs(2, 2|4). We show that the gauging of hs(2, 2|4) gives rise to a spectrum of physical massless fields which coincides with the symmetric tensor product of two AdS5 spin-1 doubletons (i.e. the N=4 SYM multiplets living on the boundary of AdS5). This product… (More)
