Gauging the full R-symmetry group in five-dimensional, N=2 Yang-Mills-Einstein-tensor supergravity - art. no. 064023

We show that certain five-dimensional, N = 2 Yang-Mills-Einstein supergravi ty theories admit the gauging of the full R-symmetry group, SU(2)(R), of th e underlying N = 2 Poincare superalgebra. This generalizes the previously s tudied Abelian gaugings of U(1)(R)subset of SU(2)(R), and completes the con struction of the most general vector and tensor field coupled five-dimensio nal, N = 2 supergravity theories with gauge interactions. The gauging of SU (2)(R) turns out to be possible only in special cases, and leads to a new t ype of scaler potential. For a large class of these theories the potential does not have any critical points.
