Resumen de Mystery boson finally earns Higgs status
New data confirms that the unsatisfyingly named "Higgs-like particle" announced at CERN last year really is a Higgs boson. Back then, the particle's discoverers were sure it was a boson, one of two types of elementary particle, and that its mass was about 126 GeV. But their data couldn't reveal all its properties. Theory dictates that a Higgs boson must have a value of zero for a quantum mechanical property called spin, and positive "parity", which can be thought of as looking the same when reflected in a mirror. Data reported at the Moriond meeting on La Thuile, Italy, last week all but nailed these two qualities.
