Description
The solution to fine tuning is one of the principal motivations for physics
beyond the standard model. However constraints on the parameter space of such
models suggest that they may also require fine tuning (although to a much lesser
extent). To compare this tuning between such models it is essential that we have
a reliable, quantitative measure of tuning. We review the measures of tuning used
in the literature and propose an alternative measure. We apply this measure to
several toy models and the MSSM with some intriguing results.
