Universal contributions to scalar masses from five dimensional supergravity

Understand

We compute the effective Kahler potential for matter fields in warped compactifications, starting from five dimensional gauged supergravity, as a function of the matter fields localization.

• We show that truncation to zero modes is inconsistent and the tree-level exchange of the massive gravitational multiplet is needed for consistency of the four-dimensional theory.
• In addition to the standard Kahler coming from dimensional reduction, we find the quartic correction coming from integrating out the gravity multiplet.
• We apply our result to the computation of scalar masses, by assuming that the SUSY breaking field is a bulk hypermultiplet.
