Jumping Through Loops: On Soft Terms from Large Volume Compactifications
read the original abstract
We subject the phenomenologically successful large volume scenario of hep-th/0502058 to a first consistency check in string theory. In particular, we consider whether the expansion of the string effective action is consistent in the presence of D-branes and O-planes. Due to the no-scale structure at tree-level, the scenario is surprisingly robust. We compute the modification of soft supersymmetry breaking terms, and find only subleading corrections. We also comment that for large-volume limits of toroidal orientifolds and fibered Calabi-Yau manifolds the corrections can be more important, and we discuss further checks that need to be performed.

Explicit construction of a chiral global embedding of Fibre Inflation with anti-D3 uplift on an h^{1,1}=4 K3-fibered Calabi-Yau, using magnetised D7-branes, a Whitney brane, and O3-planes at a conifold tip, with viabl...

Loop Blow-up Inflation: An Overview
String loop corrections in blow-up inflation generate a power-law plateau at large fields, raising the tensor-to-scalar ratio while keeping all three Standard Model location scenarios consistent with latest observatio...
