Re: And the "Standard Model" is?
"When LEP found no SUSY physicists were already casting doubt on the existence of SUSY."
Not true. Thermal models of Big Bang WIMP production predict a Dark Matter mass around 1 TeV/c2. LEP could not reach anywhere even close to that. While I did not work on LEP I was at CERN at the time and knew a lot who did and I can honestly say that I knew nobody who though the LEP results cast any doubts on SUSY - simply that the mass scale was higher than LEP could reach.
"SUSY is dead in the view of most serious physicists."
Again not true - talk to my colleagues on ATLAS. We have a huge SUSY group actively looking for it (and I'm not even a member of it!). It is true to say that the MSSM is looking somewhat constrained but you massively overstate the case by saying we think it is dead...well unless you think that none of us working on the LHC are "serious physicists". ;-) If you look at the mass limits for the ATLAS and CMS searches most of these are around 1 TeV/c2. At this scale the hierarchy problem is still very readily solvable by SUSY. However if we do not see it after the long shutdown, then I would agree that at this stage the mass limits (expected to be several TeV and rising) will start to raise issues.
"What people forget is that SUSY makes the SM worse anyway, by introducing a 100 extra parameters that can have arbitrary values. The SM has about 18, I think."
Again you misstate the case. SUSY is effectively like a second Standard Model and has all the free parameters that the Standard Model had UNTIL we measured a lot of them and found them to be zero or forbidden. For example the SM has a free parameter 'theta' which gives the strength of CP violation in strong interactions. However this is not usually listed as a free parameter because, experimentally, theta is exactly zero. So while the MSSM has 120+ free parameters many of these may well turn out to be zero if SUSY is out there and it may well be that you end up with something close to the 25 free parameters of the SM.
So by all means say that if SUSY is out there it is not as obvious as we would have naively expected it to be but, at the moment, I would completely disagree that most physicists think it is dead as an explanation of the hierarchy problem and dark matter. It's under threat - which is the best place for a theory to be because it means we have a chance to either find it or rule it out - but we are not quite there yet.
