Simple Supergravity
摘要
We present a short overview of the structure and couplings of \(4D, \mathcal {N}=1\) supergravity theories at the component level. We do so with as little technical machinery as possible, working directly with the physical on-shell fields and using explicit computations and geometrical reasoning to arrive at the result, highlighting the new properties of supersymmetry in the context of a gravitational theory.
