New York Times: Physicists working at CERN’s Large Hadron Collider said Wednesday that they had discovered a new subatomic particle that looks for all the world like the Higgs boson, a potential key to an understanding of why elementary particles have mass and indeed to the existence of diversity and life in the universe.
Dr. Heuer and others said that it was too soon to know for sure whether the new particle, which weighs in at 125 billion electron volts, one of the heaviest subatomic particles yet, fits the simplest description given by the Standard Model, the theory that has ruled physics for the last half-century, or whether it is an impostor, a single particle or even the first of many particles yet to be discovered.
