Abstract

We discuss a gauged U(1)_R supergravity on five-dimensional (5D) orbifold (S¹/Z₂) in which both a Z₂-even U(1) gauge field and the Z₂-odd graviphoton take part in the U(1) _R gauging. Based on the off-shell formulation of 5D supergravity, we analyze the structure of Fayet-Iliopoulos (FI) terms allowed in such model. Introducing a Z₂-even U(1)_R gauge field accompanies new bulk and boundary FI terms in addition to the known integrable boundary FI term which could be present in the absence of any gauged U(1)_R symmetry. Some physical consequences of these new FI terms are examined.
