New supersymmetric gauge theories: the double tensor multiplet and its interactions (original) (raw)

This research investigates the double tensor multiplet in four-dimensional N=2 supersymmetry, particularly in relation to type IIB superstring vacua. The paper outlines the on-shell realization of the supersymmetry algebra and explores interactions of the double tensor multiplet with vector and hypermultiplets, emphasizing the discovery of nontrivial coupling invariants and the absence of power-counting renormalizable couplings at dimensions ≤ 4, while detailing trilinear interactions in the dimension 5 couplings.
