Abstract: We construct spectra of supersymmetric higher spin theories in D = 4, 5 and 7 from twistors describing massless (super‐)particles on AdS spaces. A massless twistor transform is derived in a geometric way from classical kinematics. Relaxing the spin‐shell constraints on twistor space gives an infinite tower of massless states of a “higher spin particle”, generalizing previous work of Bandos et al.. This can generically be done in a number of ways, each defining the states of a distinct higher spin theory, and the method provides a systematic way of finding these. We reproduce known results in D = 4, minimal supersymmetric 5‐ and 7‐dimensional models, as well as supersymmetrisations of Vasiliev’s Sp‐models as special cases. In the latter models a dimensional enhancement takes place, meaning that the theory lives on a space of higher dimension than the original AdS space, and becomes a theory of doubletons. This talk was presented at the XIX‐th Max Born Symposium “Fundamental Interactions and Twistor‐Like Methods”, September 2004, in Wrocław, Poland.
