Did Atlas Just See The Higgs ?

It seems I am late on this one -an internal note by the Atlas collaboration seems to contain the discovery of a bump in the diphoton mass distribution from data collected in 2010 and 2011. They find a signal that seems consistent, in mass and resolution, with what one would expect from a Higgs decay, if the Higgs were sitting at 115 GeV, the value at which LEP II found some hint (a 1.7 standard deviation signal) before being shut down in 2001. Since I cannot distribute information I do not possess, let me speculate on the information that has been distributed elsewhere already. I think the signal is false, for a few reasons: read more
