Unified Geometric Theory of Gravity and Supergravity

S.W. MacDowell, F. Mansouri
Phys.Rev.Lett.38:739,1977, Erratum-ibid.38:1376,1977.

and a blog post by Jacques Distler,

In contrast to all the latest results usually discussed in the journal club,
this time I hope to say something coherent about ''MacDowell / Mansouri
gravity'', based on a paper now 30 years old. I hope to convince you that at
the least this is a nice way of reformulating the gravity and supergravity
actions and especially the appearance of a dimensionfull coupling. The
latter is related to an observation by Distler in the abovementioned blog
