A new 24+24 matter multiplet of N=2 conformal supergravity

We write down the 48+48 component multiplet of supercurrents for a rigid N=2 tensor multiplet in four spacetime dimensions along with its supersymmetry transformation law. This gives us the transformation of the linearized supergravity multiplet which couples to this supercurrent multiplet. At the linearized level, this 48+48 component supergravity multiplet decouples into the 24+24 component linearized standard Weyl multiplet known in the literature and a new 24+24 component irreducible multiplet that contains a dilaton and dilatino. By a consistent application of the supersymmetry algebra with field dependent structure constants appropriate to N=2 conformal supergravity, we find the full transformation law for this newly found multiplet. We present a set of constraints which can be consistently imposed on the new multiplet to obtain a restricted minimal 8+8 off-shell matter multiplet. We also show as an example the precise embedding of the tensor multiplet inside the new multiplet.
