The LHC will increase the proton beam energy to 4 TeV per beam when it restarts operation in March. The mass range available to the Higgs particle is already narrowed to a window of just 16 GeV. The ATLAS and CMS experiments have seen hints that a Higgs might exist in the mass range 124-126 GeV. To discover, or to rule out the Standard Model Higgs altogether, requires one more year’s worth of data. The LHC is scheduled to enter a long technical stop at the end of this year to prepare for running at its full design energy of around 7 TeV per beam.
