FLUX COMPACTIFICATIONS AND SUPERSYMMETRY BREAKING IN 6D GAUGED SUPERGRAVITY

초록

We review on a recent construction of the on-shell supersymmetric brane action for the codimension-two branes with nonzero tension in the flux compactification of a 6D chiral gauged supergravity. On dimensionally reducing on 4D gauged supergravity for a new supersymmetric unwarped background with conical branes, we consider the modulus stabilization for determining the soft masses of the scalars localized on the branes and show that the bulk U(1)(R) provides a new mechanism for mediating the SUSU breaking.
