In the Standard Model, the ratio between the top quark's mass to the neutrinos is at least about $2 \times 10^{11}$. It could rise by at least an order of magnitude in the coming years as the sensitivity of experiments measuring the neutrino masses increases.
This is only a couple of orders of magnitude less than the ratio of the supposed GUT scale to the mass of the Higgs, at approximately $10^{14}$.
Is the large ratio of masses in the Standard Model an example of a hierarchy problem in the usual sense?
