N2 - We discuss an N=2 supergravity model that interpolates the full and the partial supersymmetry breakings. In particular, we find the conditions for an N=0 Minkowski vacuum, which is continuously connected to the partial-breaking (N=1 preserving) one. The model contains multiple (Abelian) vector multiplets and a single hypermultiplet, and is constructed by employing the embedding tensor technique. We compute the mass spectrum on the Minkowski vacuum, and find some non-trivial mass relations among the massive fields. Our model allows us to choose the two supersymmetry-breaking scales independently, and to discuss the cascade supersymmetry breaking for the applications to particle phenomenology and cosmology.
