U(1)(R)-mediated supersymmetry breaking from a six-dimensional flux compactification

초록

We study the U(1)(R)-mediated supersymmetry breaking in a flux compactification of 6D chiral gauged supergravity with codimension-two branes. We consider a concrete model with manifest U(1)(R) invariance for moduli stabilization and visible sector in the context of 4D effective supergravity with gauged U(1)(R) and determine soft scalar masses in the visible sector mainly by a nonzero U(1)(R) D-term. We obtain a low energy superparticle spectrum and discuss on the implications of the obtained non-universal scalar soft masses on the SUSY phenomenology such as dark matter relic abundances.
