finally rule out a low mass Higgs boson, we are on the verge of a major change in our understanding of the fundamental nature of matter." (Also: Hooray, I can hear the webcast properly! Well done for inventing the web, Cern folk, and also for sorting out your IT) 2.15pm: CMS has released an image of the results of a proton-proton collision (main pic above) in which you can see four high-energy electrons (green lines and red towers). This shows the characteristics expected from the decay of a Higgs boson. 2.19pm: From @stevengoldfarb , who is a physicist, outreach, education and communication coordinator on Atlas experiment at Cern: "Looks like our colleagues from #CMS see similar excesses near 125 GeV. 2012 will be fun! #ATLAS #LHC #CERN #Higgs" The latest results narrow the field even more: Atlas has excluded all masses outside the range of 115 -- 130?GeV, and the CMS team has revised the range to 117 -- 127?GeV. Raising anticipation still further, each experiment separately reports that the LHC's high-energy collisions between protons generated an excess of particles that could be the products of Higgs particle production. The ATLAS result is consistent with a 125 -- 126?GeV Higgs at a statistical level of at most 3.6 standard deviations, and the CMS team reports a 124GeV signal of at most 2.6 standard deviations. In particle physics, a statistical significance of five standard deviations is considered to be proof of a particle's existence, and three standard deviations to be evidence
