| Title: |
"Hierarchy Problems in String Theory: An Overview of the LARGE Volume Scenario"
|
| Abstract: |
In a string theory context the origins of the hierarchies present in
nature are intimately tied to moduli stabilisation. I describe the LARGE
volume scenario for moduli stabilisation, its stringy origins and
how it leads to both dynamical low-scale supersymmetry breaking and
an intermediate axion scale. I describe work on embedding the Standard Model
into this setup using configurations of D3/D7 branes at singularities.
This gives a generic phenomenological expectation that Standard Model
matter is charged under new, potentially light, gauge bosons with
hierarchically small couplings.
