Flavor structure with multi moduli in 5D SUGRA
Hiroyuki Abe, Yutaka Sakamura
We investigate 5-dimensional supergravity on S^1/Z_2 with a physical Z_2-odd vector multiplet, which yields an additional modulus other than the radion. We find additional terms in…
Radius stabilization in 5D SUGRA models on orbifold
Yutaka Sakamura
We study a four-dimensional effective theory of the five-dimensional (5D) gauged supergravity with a universal hypermultiplet and perturbative superpotential terms at the orbifold…
Moduli stabilization in 5D gauged supergravity with universal hypermultiplet and boundary superpotentials
Hiroyuki Abe, Yutaka Sakamura
We study a four-dimensional effective theory of the five-dimensional (5D) gauged supergravity with a universal hypermultiplet and perturbative superpotential terms at the orbifold…
Geometry mediated supersymmetry breaking
Yutaka Sakamura
We investigate SUSY breaking mediated through the deformation of the spacetime geometry due to the backreaction of a nontrivial configuration of a bulk scalar field. To illustrate…
SUSY Breaking by stable non-BPS configurations
Nobuhito Maru, Norisuke Sakai, Yutaka Sakamura +1
A simple mechanism for SUSY breaking is proposed due to the coexistence of BPS domain walls. It requires no messenger fields nor complicated SUSY breaking sector on any of the wall…
