Higgs particle: or Higgs boson Carrier of an all-pervading fundamental field (Higgs field) that is hypothesized as a means of endowing mass on some elementary particles through its interactions with them.

The Higgs mechanism explains why the carriers of the weak force are heavy, while the carrier of the electromagnetic force has a mass of zero. There is no direct experimental evidence for the existence of either the Higgs particle or the Higgs field
W particle: Electrically charged subatomic particle that transmits the weak force, which governs radioactive decay (see radioactivity) in some atomic nuclei. The discovery of the W particle in 1983 by teams led by Carlo Rubbia and Simon van der Meer confirmed the electroweak theory, which explains that the electromagnetic force and the weak force are manifestations of the same interaction. The weak force is exchanged via three types of particles, two charged and one neutral. The charged particles are designated W^+ and W^- according to the sign of their charge, and the neutral particle is the Z particle. The W particle has a mass about 80 times that of the proton, which gives the weak force a very short range
Z particle: Electrically neutral carrier of the weak force and the neutral partner of the electrically charged W particle. It is nearly 100 times more massive than the proton and has a lifetime of only about 10^-25 second. Z particles were first observed in 1983 by Carlo Rubbia and Simon van der Meer at CERN. Further studies have shown a natural variation in mass that is related to the particle's lifetime through the uncertainty principle.

By the early 1930s it was found that the nucleus is composed of even smaller particles, called protons and neutrons.

In 1905, by demonstrating the photoelectric effect, Albert Einstein showed that light, which until then had been thought of as a form of electromagnetic wave (see electromagnetic radiation), must also be thought of as localized in packets of discrete energy (see photon). In 1924 Louis-Victor Broglie proposed that electrons have wave properties such as wavelength and frequency; their wavelike nature was experimentally established in 1927 by the demonstration of their diffraction. The theory of quantum electrodynamics combines the wave theory and the particle theory of electromagnetic radiation
