The Higgs Particle:
A Higgs Particle Decaying to 2 Z Particles

The Higgs particle is expected to be produced in collisions when a gluon from each of the protons merges in a high energy collision – a gluon fusion.

      • We know that the mass of the Higgs particle is large and therefore the two interacting gluons need to have high energy to be able to produce the Higgs particle. The Higgs particle will be produced very rarely, requiring a large number of particle collisions before one has a good chance to find it. The Higgs particle decays instantaneously, and can decay in several ways. A particle with a mass around 126 GeV, compatible with being the Higgs particle, has recently been discovered by the ATLAS and CMS experiments at CERN.
