'Nonchiral' primary superfields in the Ad(d+1)/CFTd correspondence

We consider some long multiplets describing bulk massive excitations of M-t heory two-branes and IIB string three-branes which correspond to 'nonchiral ' primary operators of the boundary OSp(8/4) and SU(2, 2/4) superconformal field theories. Examples of such multiplets are the 'radial' modes on the b ranes, including up to spin 4 excitations, which may be then considered as prototypes of states which are not described by the K-K spectrum of the cor responding supergravity theories on Ad S-4 x S-7 and Ad S-5 x S-5, respecti vely.
