Off-shell higher spin N=2 supermultiplets in three dimensions

Understand

Off-shell higher spin N=2 supermultiplets in three spacetime dimensions (3D) are presented in this paper.

• We propose gauge prepotentials for higher spin superconformal gravity and construct the corresponding gauge-invariant field strengths, which are proved to be conformal primary superfields.
• These field strengths are higher spin generalisations of the (linearised) N=2 super-Cotton tensor, which controls the superspace geometry of conformal supergravity.
• We also construct the higher spin extensions of the linearised N=2 conformal supergravity action.
