From F-theory GUTs to the LHC

Understand

This paper provides an overview to three recent papers on the bottom up approach to GUTs in F-theory.

• We assume only a minimal familiarity with string theory and phenomenology.
• After explaining the potential for predictive string phenomenology within this framework, we introduce the ingredients of F-theory GUTs, and show how these models naturally address various puzzles in four-dimensional GUT models.
• We next describe how supersymmetry is broken, and show that in a broad class of models, solving the mu/B mu problem requires a specific scale of supersymmetry breaking consistent with a particular deformation of the gauge mediation scenario.
