| ABSTRACT: |
When studying models of New Physics, usually many
points in the parameter space of the model violate existing
experimental constraints. We show that the fractal
dimension of that part of parameter space that satisfies
those constraints is a good measure of fine tuning. We
introduce the concept of fractal dimensions, use a toy
model to show that the fractal dimension measures fine
tuning and then show examples from several models of
New Physics. |
