Unless there is a symmetry reason to protect the Higgs mass near the
electroweak scale, one loop effects will give large corrections. Is it
super-symmetry or is it something else ? Or is it some extra dimensional
mechanism which is working ? Or is it purely fine tuning of parameters ?
Depending on existing data is there a way to differentiate
between competing models ?
There was a calculation of s,t,u parameters involving one loop
calculations involving standard model fields. Those could
differentiate between different models of new physics. For example
supersymmetry was preferred over technicolor models.
In that spirit, some calculations should exist, which will tell
us about the chances of discovering superpartners or
other new physics candidates.
