LHC sees hint of boson heavier than Higgs .... The results largely match a rumour that has been circulating on social media and blogs for several days: that both the CMS and ATLAS detectors at the LHC have seen an unexpected excess of pairs of photons, together carrying around 750 gigaelectronvolts (GeV) of energy, in the debris of their protonproton collisions. This could be a tell-tale sign of a new particle also a boson, but not necessarily similar to the Higgs decaying into two photons of equivalent energy. If so, the particle would be about four times more massive than the next heaviest particle discovered so far, the top quark, and six times more massive than the Higgs. ... Intriguing bump In both cases, the statistical significances were very low. Marumi Kado of the Linear Accelerator Laboratory at the University of Paris-Sud said that his experiment, ATLAS, had detected about 40 more pairs of photons than would have been expected from the predictions of the standard model of particle physics. Jim Olsen of Princeton University in New Jersey reported that CMS saw merely ten. Neither team would have mentioned the excesses had the other experiment had not seen an almost identical hint. It is a little intriguing, says ATLAS spokesperson Dave Charlton of the University of Birmingham, UK. But it can happen by coincidence. In particle physics, statistical bumps such as this come and go all the time. If this one turns out to be a real particle, it would be a total game-changer, says Gian Francesco Giudice, a CERN theorist who is not a member of either ATLAS or CMS. Experimenters have spent decades validating the standard model, and the Higgs was the last missing piece in that picture. A much heavier particle would open an entire new chapter in the field, he says. The Higgs boson pales in comparison, in terms of novelty. |
Anyone car to elaborate on the game-changer quote?
Would we finally be able to open wormholes or travel to other universes? ;)
Ok, but seriously, what would be the big deal?
