"On Sequestering and De-Coupling in Stabilized String Models"*

Location: Bloomberg Lecture Hall

Time: 2:30 PM

Speaker(s): David Marsh, Cornell University

*Description:* I will describe recent efforts to understand the 
mediation of supersymmetry breaking in stabilized compactifications of 
type IIB string theory. By geometrically separating the visible sector 
from the supersymmetry breaking effects one may hope to achieve 
sequestered supersymmetry breaking and much ameliorated constraints from 
bounds on flavor changing neutral currents. However, in this talk I will 
discuss how non-perturbative superpotential cross-couplings between the 
visible sector and the Khler moduli may spoil sequestering and introduce 
a sensitivity to the global details of the compactification. As a simple 
example, I will describe the structure of these `de-sequestering 
operators for a class of visible sectors realized by D-branes probing an 
orbifold singularity, and I will discuss their importance in the KKLT 
and LVS moduli stabilization scenarios.
