According to this talk by CERN's Fabio Zwirner, 1 inverse femtobarn is sufficient to eliminate a Higgs above 120 GeV. Now, the LHC has achieved that value a few days ago. So I am looking forward to the corresponding data analysis!
Above all, I am looking forward to see the faces of CERN managers when they will admit that there is no Higgs boson. And to the Homeric laughter that will follow across the world.
The LHC will then be renamed "Tunnel of Babylon". (The expression is my copyright...)
Or are they holding back the result already, to avoid loosing face?
