I learned via Physics World that CERN will hold a press conference on Wednesday July 4 to give an “Update on the search for the Higgs Boson”. More information has just appeared (including a press release here), showing that there will be a 2 hour seminar on the results starting at 9am Geneva time, followed by a press conference at 11am.
Reports from the experiments indicate that at least one of them, if not both, will reach the 5 sigma level of significance for the Higgs signal, when they combine 2011 and 2012 data and the most sensitive channels. So, this will definitely be the long-awaited Higgs discovery announcement, and party-time for HEP physicists.
One could note that the last major announcement of the discovery of a new elementary particle at CERN was also made on a Wednesday, July 4, back in 1984. That one didn’t work out so well, but things are very different now, with results from two independent experiments and a high standard of evidence.
