2000 scientists at Fermilab announce the first direct evidence for the tau neutrino, the third kind of neutrino in particle physics. [30] 2000 CERN announced quark-gluon plasma, a new phase of matter. [34] 2001 the Sudbury Neutrino Observatory (Canada) confirm the existence of neutrino oscillations.
This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
Timeline of particle physics technology. 1896 - Charles Wilson discovers that energetic particles produce droplet tracks in supersaturated gases. 1897-1901 - Discovery of the Townsend discharge by John Sealy Townsend. 1908 - Hans Geiger and Ernest Rutherford use the Townsend discharge principle to detect alpha particles.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.

Strangelet, hypothetical particle that could form matter consisting of strange quarks. R-hadron, bound particle of a quark and a supersymmetric particle. T meson, hypothetical mesons composed of a top quark and one additional subatomic particle. Examples include the theta meson, formed by a top and an anti-top.
refers to the real particle which is actually observed and which is close to the η 8. The η′ is the observed particle close to η 1. [10] The η and η′ particles are closely related to the better-known neutral pion π 0, where
Throughout the 1950s and 1960s, improvements in particle accelerators and particle detectors led to a bewildering variety of particles found in high-energy experiments. The term elementary particle came to refer to dozens of particles, most of them unstable. It prompted Wolfgang Pauli's remark: "Had I foreseen this, I would have gone into botany".
