TL;DR: In this paper, it was shown that the quantization of a superparticle propagating in an N = 1, D = 4 superspace extended with tensorial coordinates results in an infinite tower of massless spin states satisfying the Vasiliev unfolded equations for free higher spin fields in flat and AdS4 N =1 superspace.
Abstract: It is shown that the quantization of a superparticle propagating in an N = 1, D = 4 superspace extended with tensorial coordinates results in an infinite tower of massless spin states satisfying the Vasiliev unfolded equations for free higher spin fields in flat and AdS4 N = 1 superspace. The tensorial extension of the AdS4 superspace is proved to be a supergroup manifold OSp(1|4). The model is manifestly invariant under OSp(N|8) (N = 1,2) superconformal symmetry. As a byproduct, we find that the Cartan forms of arbitrary Sp(2n) and OSp(1|2n) groups are GL(2n) flat, i.e. they are equivalent to flat Cartan forms up to an exactly determined GL(2n) rotation. This property is crucial for carrying out the quantization of the particle model on OSp(1|4) and getting the higher spin field dynamics in super AdS4, which can be performed in a way analogous to the flat case.

TL;DR: In this paper, the theory of higher spin fields in flat D = 4 space and in AdS(4) emerges as a result of the quantization of a superparticle propagating in so called tensorial superspaces which have the property of a generalized conformal or simply General Linear (GL) flatness.
Abstract: A main purpose of this paper is to explain how the theory of higher spin fields in flat D=4 space and in AdS(4) emerges as a result of the quantization of a superparticle propagating in so called tensorial superspaces which have the property of a `generalized conformal' or simply General Linear (GL) flatness.

TL;DR: A supersymmetric and kappa-invariant action for describing coincident D0-branes with non-abelian matter fields on their worldline was proposed in this paper.
Abstract: We propose a generic supersymmetric and kappa-invariant action for describing coincident D0-branes with non-abelian matter fields on their worldline. The action is shown to be in agreement with the Matrix Theory limit of the ND0-brane effective action.
