Clarification: the Higgs, the missing piece

Physicists at the CERN laboratory in Switzerland may have finally found the Higgs, the missing piece from particle physicists' Standard Model that explains why all other particles have mass.

A diagram summarizing the tree-level interactions between elementary particles described in the Standard Model. Vertices (darkened circles) represent types of particles, and edges (blue arcs) connecting them represent interactions that can take place. The organization of the diagram is as follows: the top row of vertices (leptons and quarks) are the matter particles; the second row of vertices (photon, W/Z, gluons) are the force mediating particles; and the bottom row is the Higgs boson.
