Description
The D-terms induced by gauge theory fluxes in the context of 6-dimensional
supergravity models are discussed. On the one hand, this is arguably the simplest
concrete setting in which the controversial idea of `D-term uplifts' can be
investigated. On the other hand, it is a very plausible intermediate step on the way
from a 10d string theory model to 4d phenomenology. Our specific results include the
flux-induced one-loop correction to the scalar potential coming from charged
hypermultiplets. Furthermore, we comment on the interplay of gauge theory fluxes and
gaugino condensation in the present context, demonstrate explicitly how the D-term
arises from the gauging of one of the compactification moduli, and briefly discuss
further ingredients that may be required for the construction of a phenomenologically
viable model. In particular, we show how the 6d dilaton and volume moduli can be
simultaneously stabilized, in the spirit of KKLT, by the combination of an R symmetry
twist, a gaugino condensate, and a flux-induced D-term.
