Aspects of Weyl supergravity
Abstract In this paper we study the spectrum of all conformal, N $$ \mathcal{N} $$-extended supergravities ( N $$ \mathcal{N} $$ = 1, 2, 3, 4) in four space-time dimensions. When these theories are obtained as massless limit of Einstein plus Weyl2 supergravity, the appropriate counting of the enhanc...
