On July 4, 2012, physicists announced the groundbreaking discovery of a subatomic particle that was "consistent" with the Higgs boson. Using data from two Large Hadron Collider (LHC) experiments - CMS and ATLAS - something with the approximate energy of the theoretical particle had been spotted.
"We have observed a new boson," announced Joe Incandela, CMS lead physicist, to cheers from the audience at the special meeting in Geneva, Switzerland. Had the final piece of the Standard Model finally been found? Was this the end of physics as we knew it?
A year after that historic day, physicists are still trying to characterize this "new boson," and although it certainly looks like the much sought-after Higgs boson, can the quantum hunt finally be laid to rest?

Well, in typical particle physics style, scientists are still working on it.
"We have established without a doubt that we have a new particle, and that it is a boson. What remains to be done is confirm that it is a Higgs," said physicist Pauline Gagnon, CERN physicist and member of the 2012 discovery team.
