Gauged $U(1)_R$ supergravity on orbifold

Abstract

We discuss a gauged $U(1)_R$ supergravity on five-dimensional orbifold ($S^1/Z_2$) in which a $Z_2$-even U(1) gauge field takes part in the $U(1)_R$ gauging, and show the structure of Fayet-Iliopoulos (FI) terms allowed in such model. Some physical consequences of the FI terms are examined.Comment: 4 pages, 8 figures, talk presented at the 11th International Symposium on Particles, Strings and Cosmology (PASCOS'05), May 30 - June 4, 2005, Gyeongju, Kore
