Title: 
Hypermultiplets and conformal supergravity in projective/harmonic superspace
Abstract: 

A description of general off-shell hypermultiplets with 4D N=2 supersymmetry requires the introduction of an auxiliary manifold associated with the SU(2) R-symmetry group. The resulting structure, formulated either as projective or harmonic superspace, naturally provides a framework for constructing hypermultiplet actions both in flat and curved spacetime. I will discuss recent progress toward a unified treatment of projective/harmonic superspace in a supergravity setting and describe how their complementary descriptions of target space complex geometry can be understood.
