  We continue the study of a class of string-motivated effective supergravity
theories in light of current data from the CERN Large Hadron Collider (LHC). In
this installment we consider Type IIB string theory compactified on a
Calabi-Yau orientifold in the presence of fluxes, in the manner originally
formulated by Kachru, et al. We allow for a variety of potential uplift
mechanisms and embeddings of the Standard Model field content into D3 and D7
brane configurations. We find that an uplift sector independent of the Kahler
moduli, as is the case with anti-D3 branes, is inconsistent with data unless
the matter and Higgs sectors are localized on D7 branes exclusively, or are
confined to twisted sectors between D3 and D7 branes. We identify regions of
parameter space for all possible D-brane configurations that remain consistent
with PLANCK observations on the dark matter relic density and measurements of
the CP-even Higgs mass at the LHC. Constraints arising from LHC searches at 8
TeV center-of-mass energies, and the LUX dark matter detection experiment, are
discussed. The discovery prospects for the remaining parameter space at dark
matter direct detection experiments are described, and signatures for detection
of superpartners at the LHC, with center-of-mass energy of 14 TeV, are
analyzed.
