Particle Discovered Last Year Looking More Like The HiggsCategory: Science & Technology

Last year researchers discovered a particle using the Large Hadron Collider during its search for the Higgs boson, the particle believed to give other particles their mass. Though the known properties of the discovered particle roughly matched what was theoretically expected for the Higgs boson, there was not enough evidence at the time to certify it was anything but a boson. Now, as reported by New Scientist, researchers are reporting new data which strongly supports that the particle is indeed the predicted particle, but there is still not enough evidence to certify that.
The Higgs boson is the last major particle predicted by the Standard Model of particle physics, and is believed to give other particles their mass. Since it was first postulated researchers have been looking for it and creating larger, more powerful particle accelerators towards that end, including CERN's Large Hadron Collider. At a recent conference new information was presented that strongly indicates the discovered particle has two properties it must have to be the Higgs boson. Before this the researchers could only say they were working with a 'Higgs-like' boson.
Technically though, the particle is still just 'Higgs-like' as much more data will be needed before proving it is the Higgs boson. Exactly when that may happen is hard to say as the LHC is currently powered down for maintenance and will be for some time yet.
