The Higgs boson helps explain why particles have the mass they do. The Higgs particle that the LHC has found possesses a mass of approximately 126 giga-electron volts (GeV)—roughly the combined mass of 126 protons (hydrogen nuclei). (One GeV equals a billion electron volts.)
This image depicts a vintage logo for the quark, the elementary particles that make up hadrons like protons and neutrons. There are 6 flavors of quarks, as represented by the 6 letters at the top. The quark was theorized by Gell-Man and Zweig in 1964. This image is great for particle physicists or science lovers in general.
