Particle shower — In particle physics, a shower is a cascade of secondary particles produced as the result of a high energy particle interacting with dense matter. The incoming particle interacts, producing multiple new particles with lesser energy; each of these… … 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

Interacting Boson Approximation — Bei der Interacting Boson Approximation (IBA) handelt es sich um Näherungsverfahren um die Struktur von Atomkernen zu beschreiben. Oft wird dieses Verfahren auch als Interacting Boson Model (IBM) bezeichnet. Das Modell eignet sich vor allem für… … Deutsch Wikipedia
Particle zoo — In particle physics, the term particle zoo is used colloquially to describe a relatively extensive list of the known elementary particles that almost look like hundreds of species in the zoo.The situation was particularly confusing in the late… … Wikipedia
Interacting boson model — The interacting boson model (IBM) is a model in nuclear physics in whichnucleons (protons or neutrons) pair up, essentiallyacting as a single particle with boson properties, withintegral spin of 0, 2 or 4.The IBM I treats both types of nucleons… … Wikipedia
Cryogenic particle detectors — operate at very low temperature, typically only a few degrees above absolute zero. These sensors interact with an energetic elementary particle (such as a photon) and deliver a signal which can be related to the type of particle and the nature of … Wikipedia
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
Virtual particle — In physics, a virtual particle is a particle that exists for a limited time and space, introducing uncertainty in their energy and momentum due to the Heisenberg Uncertainty Principle. (Indeed, because energy and momentum in quantum mechanics are … Wikipedia
Dissipative particle dynamics — (DPD) is a stochastic simulation technique for simulating the dynamic and rheological properties of simple and complex fluids. It was initially devised by Hoogerbrugge and Koelman [1][2] to avoid the lattice artifacts of the so called lattice gas … Wikipedia
