SUMMARY:Open string moduli and multi-branched potentials\, Theory Semi
 nar (High Energy/Cosmology)\, Gianluca Zoccarato\, Hong Kong IAS
DESCRIPTION:In this talk we consider type II string compactifications 
 on Calabi-Yau orientifolds with fluxes and D-branes and analyse the F-
 term scalar potential that simultaneously involves closed and open str
 ing modes. We focus on the cases of type IIA orientifolds with D6-bran
 es and type IIB orientifolds with D7-branes. In type IIA models with D
 6-branes this potential can be directly computed by integrating out Mi
 nkowski three-forms showing therefore a multi-branched structure along
  the space of lifted open string moduli in which discrete shifts of br
 ane moduli are compensated by changes in the RR flux quanta. To obtain
  the correct form of the scalar potential we find strong constraints o
 n the Kähler potential implying some interesting no-scale relations o
 beyed by the Kähler metric. Importantly the addition of open string m
 oduli breaks the factorisation between complex structure and Kähler m
 oduli spaces. We conclude by discussing the mirror dual picture of typ
 e IIB flux compactifications with D7-brane Wilson lines.
