Stefano Bellucci, Stefania De Matteo
The occurrence of a field in the formal structure of a quantum field theory does not by itself establish the existence of a corresponding asymptotic particle. We develop a structur…

Structural Origin of the Gravitino Mass Term: Geometric and Supergravity Perspectives
Stefano Bellucci, Stefania De Matteo
We identify a minimal superspace projector that uniquely selects the Rarita Schwinger mass bilinear in four-dimensional N=1 supergravity. Working in a reduced superspace with a sin…
