Higgs Boson Live Blog: Analysis of the CERN Announcement

Philip E. Gibbs


We report here live on LHC Higgs results announcement by CERN on December 13, 2011. The result is very convincing if one starts from the assumption that there should be a Higgs Boson somewhere in the range. Everywhere is ruled out except 115 GeV to 130 GeV and within that window there is a signal with the right strength at around 125 GeV with 3 sigma significance. CERN will have to wait for that to reach 5 sigma to claim discovery and next year’s data should be enough to get there or almost. I calculate that they will need 25/fb per experiment at 7 TeV to make the discovery. A big congratulation goes to everyone from the LHC, ATLAS and CMS who found the clear hints of Higgs when it hid in the hardest place.
