Here’s an excerpt:
These results provide conclusive evidence for the discovery of a new particle with mass. The signal strength parameter ? has the value 1.4±0.3 at the fitted mass, which is consistent with the SM Higgs boson hypothesis ?=1. The decays to pairs of vector bosons whose net electric charge is zero identify the new particle as a neutral boson.
Before this discovery didn’t know what gave particles mass. We now know a kind of particle, neutral boson (or Higgs Boson after Peter Higgs) does this. So this discovery explains a bit more of the standard model of physics. They need to do some more research to find out if other kinds of Higgs Boson’s exist and if they can, a whole new range of discoveries in particle physics are on the horizon.. like proving supersymmetry maybe.
Exciting times for these physicists!
