The Fayet Sohnius hypermultiplet with gauged central charge coincides on-shell with N=2 supersymmetric electrodynamics. The gauge couplings of the vector-tensor multiplet turn out to be nonpolynomial.10 pages, LaTeX, uses AMS-LaTeX. Ansatz for constraints on L changed, reference addedHigh Energy Physics - Theorytext
