Transverse mass — The transverse mass is a useful thing to define for use in particle physics. In natural units it is:::m {T}^2 = m^2 + p {x}^2 + p {y}^2 ,:where the z direction is along the beam pipe and so:p x and p y are the momentum perpendicular to the beam… … Wikipedia
PHENIX — (Pioneering High Energy Nuclear Interactions eXperiment) is one of the four experiments at the Relativistic Heavy Ion Collider located at the Brookhaven National Laboratory. Its research goals are the discovery and the examination of the quark… … Wikipedia
Stochastic cooling — is a form of particle beam cooling. It is used in some particle accelerators and storage rings to control the emittance of the particle beams in the machine. This process uses the electrical signals that the individual charged particles generate… … Wikipedia

Uncertainty principle — In quantum physics, the Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the… … Wikipedia
Hermetic detector — In particle physics, a hermetic detector (also called a 4π detector) is a particle detector designed to observe all possible decay products of an interaction between subatomic particles in a collider by covering as large an area around the… … Wikipedia
Snell's law — In optics and physics, Snell s law (also known as Descartes law, the Snell–Descartes law, and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other… … Wikipedia
Ionization cooling — Physical Principle = Ionization cooling is a process by which the beam emittance of a beam of particles may be reduced [G.I. Budker, in: Proceedings of 15th International Conference on High Energy Physics, Kiev, 1970A.N. Skrinsky, Intersecting… … Wikipedia
Parton (particle physics) — In particle physics, the parton model was proposed by Richard Feynman in 1969 as a way to analyze high energy hadron collisions. [R. P. Feynman, Proceedings of the 3rd Topical Conference on High Energy Collision of Hadrons, Stony Brook, N. Y.… … Wikipedia
