  I'd be very happy if there was no evidence for it existing. Then things would get interesting.

    I'm totally with Troy on this one.
    
    There must be an answer to the question as to where mass comes from that's not as mathematically messy as the Standard Model, but that doesn't necessarily require any new emergent property like the Higgs Mechanic.
    
    Hence my continuing use of the slightly derisive phrase "The New Ether"!
    
    And I will happily continue to use that phrase until evidence of the Higgs boson is found. That would blow my mind much more than if it were not found.

  It might be as low as between 60 - 70 GeV.
  I remember, about a year and a half ago, I attended a colloquium. There they spoke of these numbers, (I think). I don't remember the exact number, but the range was somewhere there.
  
  They did a superposition of two narrow ranges, and their intersection fell into a small window.

    Using data that has been generated over the last several years by Fermilab's Tevatron, a collaboration between DZero and CDF found that the Higgs particle cannot exist at masses between 160 and 170 GeV, given a 95 percent confidence level. If one relaxes the level of confidence, then this exclusion range expands to cover masses between about 157 and 181 GeV.

      Previous work has put lower and upper limits on the mass of this particle. CERN's Large Electron-Positron collider has been unable to find the Higgs particle at masses below 114 GeV, setting this as a lower bound for the mass. Studies of the electroweak force suggest that the Higgs particle must weigh less than 185 GeV. Now, work by a collaboration of the DZero and CDF particle discovery groups (each of those are collaborations in their own right) has narrowed this window even further.

      Oh, so my "general" number was in the correct "vicinity", on 160-170 GeV, not 60-70 GeV.
      I see. Thanks, Curry.
      
      It's been a while ago; so, I do not remember that colloquium that well anymore.
