Building on the five-dimensional constructions in hep-th/0601177, we provide a unified description of four-dimensional = 2 superconformal off-shell multiplets in projective superspace, including a realization in terms of = 1 superfields. In particular, superconformal polar multiplets are consistently defined for the first time. We present new 4D = 2 superconformal sigma-models described by polar multiplets. Such sigma-models realize general superconformal couplings in projective superspace, but…

On 2D N = (4,4) superspace supergravity

We review some recent results obtained in studying superspa.ee formulations of 2D N = (4,4) matter-coupled supergravity. For a superspace geometry described by the minimal supergravity multiplet, we

Super-Weyl invariance in 5D supergravity

We propose a superspace formulation for the Weyl multiplet of N=1 conformal supergravity in five dimensions. The corresponding superspace constraints are invariant under super-Weyl transformations

Projective multiplets and hyperkähler cones in conformal supergravity

A bstractProjective superspace provides a natural framework for the construction of actions coupling hypermultiplets to conformal supergravity. We review how the off-shell actions are formulated in

Conformal supergravity in five dimensions: new approach and applications

A bstractWe develop a new off-shell formulation for five-dimensional (5D) conformal supergravity obtained by gauging the 5D superconformal algebra in superspace. An important property of the

Different representations for the action principle in 4D N = 2 supergravity

Within the superspace formulation for four-dimensional N = 2 matter-coupled supergravity developed in arXiv:0805.4683, we elaborate two approaches to reduce the superfield action to components. One

N=1 Superconformal Symmetry in Four-Dimensional Quantum Field Theory

The implications of N=1 superconformal symmetry for four dimensional quantum field theories are studied. Superconformal covariant expressions for two- and three-point functions of quasi-primary

A superspace survey

A survey of superspaces associated with four-dimensional Minkowski spacetime is given from a superconformal perspective. The discussion begins in the complex setting and focuses on a class of
