Particle decay — is the spontaneous process of one elementary particle transforming into other elementary particles. During this process, an elementary particle becomes a different particle with less mass and an intermediate particle such as W boson in muon decay … Wikipedia
Particle radiation — is the radiation of energy by means of fast moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.Due to the wave particle duality, all… … Wikipedia
Particle physics in cosmology — Particle physics, which deals with the interactions of elementary particles at high energies, is an important component of cosmological models of the early universe, when the universe was dominated by radiation and its average energy density was… … Wikipedia
particle accelerator — accelerator (def. 7). [1945 50] * * * Device that accelerates a beam of fast moving, electrically charged atoms (ions) or subatomic particles. Accelerators are used to study the structure of atomic nuclei (see atom) and the nature of subatomic… … Universalium
particle — 1. A very small piece or portion of anything. 2. An elementary p. such as a proton or electron. [L. particula, dim. of pars, part] alpha p. (α) a p. consisting of two neutrons and two protons, with a positive charge (2e+); emitted energetically… … Medical dictionary
subatomic particle — or elementary particle Any of various self contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but… … Universalium
Smoothed particle hydrodynamics — (SPH) is a computational method used for simulating fluid flows. It has been used in many fields of research, including astrophysics, ballistics, vulcanology and oceanology. It is a mesh free Lagrangian method (where the co ordinates move with… … Wikipedia
sigma particle — noun see sigma II * * * Physics. an unstable hyperon having positive, negative, or zero electric charge and strangeness 1. Symbolically represented by the capital greek letter Sigma. [1960 65] * * * sigma particle, an unstable elementary particle … Useful english dictionary
Z particle — n. Particle Physics the electrically neutral weakon with a mass of 91.2 GeV/c2, which is c. 178,000 times the mass of an electron: see W PARTICLE * * * Electrically neutral carrier of the weak force and the neutral partner of the electrically… … Universalium
Timeline of particle discoveries — 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… … Wikipedia
