RT info:eu-repo/semantics/masterThesis T1 Local supersymmetry in supergravity A1 González Fernández, Daniel A2 Universidad de Valladolid. Facultad de Ciencias K1 Supersymmetry K1 Supergravity K1 Lagrangians formalism AB We have studied the local supersymmetry in two D = 4 supergravity models, withN = 1 and N = 2, given the Lagrangians. We have used a simple method based onthe differential of the action H, which provides an alternative systematic derivation ofthe gauge field variations in the first order formalism. This method may be used to findnon-relativistic limits of supergravity models.
