Titre Symmetries and spectrum of conformal higher-spin gravity
Résumé Conformal higher-spin gravity is a higher-spin extension of Weyl gravity which, despite being non-unitary, provides a remarkable example of a perturbatively local interacting higher-spin theory, consistent with minimal coupling to gravity around a flat background. The linearized spectrum and the algebra of global symmetries of conformal higher-spin gravity decompose into infinitely many representations of the conformal algebra. Their characters involve divergent sums over spins. We propose a suitable regularization adapted to their evaluation and observe that their characters are actually equal. This confirms previous observations on a remarkable rearrangement of dynamical degrees of freedom in conformal higher-spin gravity after regularization.
