CERN news statement
Geneva 7 February 2012. The Standard Model Higgs search analyses presented at CERN by the ATLAS and CMS collaborations at a seminar in December last year were today submitted for publication in the journal Physics Letters B. After further analysis, the statistical significance of the measurements remains close to that presented at the seminar, underlining the conclusion that the Standard Model Higgs boson, if it exists, is most likely to have a mass constrained to the range 116-131 GeV by the ATLAS experiment, and 115-127 GeV by CMS. Tantalising hints have been seen by both experiments in the region 124-126 GeV; however, these are not strong enough to claim a discovery.
“Our Standard Model Higgs analysis with data collected so far leaves us in a very exciting position for 2012,” said CERN’s Research Director Sergio Bertolucci. “With the data we collect this year, we will definitely be able to confirm or rule out a Standard Model Higgs.”
