Supergravity in Five Dimensions

We study compactification of five dimensional ungauged N = 2 supergravity coupled to vectorand hypermultiplets on orbifold S/Z2. In the model, the vector multiplets scalar manifold is arbitrary while the hypermultiplet scalars span a generalized self dual Einstein manifold constructed by Calderbank and Pedersen. The bosonic and the fermionic sectors of the low energy effective N = 1 supergravity in four dimensions are derived.
