# On superconformal projective hypermultiplets

@article{Kuzenko2007OnSP, title={On superconformal projective hypermultiplets}, author={Sergei M. Kuzenko}, journal={Journal of High Energy Physics}, year={2007}, volume={2007}, pages={010-010} }

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…
