Loop Fayet-Iliopoulos terms in $T^2/Z_2$ models: instability and moduli stabilization

Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1

We study Fayet-Iliopoulos (FI) terms of six-dimensional supersymmetric Abelian gauge theory compactified on a $T^2/Z_2$ orbifold. Such orbifold compactifications can lead to locali…
