Quark and Lepton Masses from Gaussian Landscapes

Understand

The flavor structure of the Standard Model might arise from random selection on a landscape.

• We propose a class of simple models, ``Gaussian landscapes,'' where Yukawa couplings derive from overlap integrals of Gaussian wavefunctions on extra-dimensions.
• Statistics of vacua are generated by scanning the peak positions of these zero-modes, giving probability distributions for all flavor observables.
• Gaussian landscapes can broadly account for all observed flavor patterns with very few free parameters.
