On 4 July, 2012, the ATLAS experiment presented a preview of its updated results on the search for the Higgs Boson. The results were shown at a seminar held jointly at CERN and via video link at ICHEP, the International Conference for High Energy Physics in Melbourne, Australia, where detailed analyses will be presented later this week. At CERN, preliminary results were presented to scientists on site and via webcast to their colleagues located in hundreds of institutions around the world.
The LHC 2012 run at a beam energy of 4 TeV has started, corresponding to a collision energy of 8 TeV, compared with the 7 TeV runs in 2010 and 2011. The data target for 2012 is 15 inverse femtobarns for ATLAS (and CMS), three times larger than the total until now. The LHC is scheduled to enter a long technical stop at the end of 2012 to prepare for running at its full design energy of around 7 TeV per beam.
The latest update of the ATLAS searches for the Standard Model Higgs boson was presented at a CERN seminar on December 13, 2011. As stated in the CERN press release, the new ATLAS and CMS results are "sufficient to make significant progress in the search for the Higgs boson, but not enough to make any conclusive statement on the existence or non-existence of the elusive Higgs. Tantalising hints have been seen by both experiments in the same mass region, but these are not yet strong enough to claim a discovery."
The ATLAS Collaboration is pleased to be presenting its latest results at the Lepton Photon 2011 conference in Mumbai 22-27 August 2011.
