Geography of Fields in Extra Dimensions: String Theory Lessons for Particle Physics

Understand

String theoretical ideas might be relevant for particle physics model building.

• Ideally one would hope to find a unified theory of all fundamental interactions.
• There are only few consistent string theories in D=10 or 11 space-time dimensions, but a huge landscape in D=4.
• We have to explore this landscape to identify models that describe the known phenomena of particle physics.
