Revisiting instabilities of $S^1/Z_2$ models with loop-induced Fayet-Iliopoulos terms

Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1

We study Fayet-Iliopoulos (FI) terms of 5-dimensional supersymmetric $U(1)$ gauge theory compactified on $S^1/Z_2$. In this model, loop diagrams including matter hypermultiplets an…
