Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation.The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, but ordinary matter is made only from the first fermion generation.

The calculation of scattering amplitudes in theoretical particle physics requires the use of some rather large and complicated integrals over a large number of variables. These integrals do, however, have a regular structure, and may be represented as Feynman diagrams.The appeal of the Feynman diagrams is strong, as it allows for a simple visual presentation of what would …

The Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin, even (positive) parity, no electric charge, and no colour charge, …

The Superconducting Super Collider (SSC) (also nicknamed the desertron) was a particle accelerator complex under construction in the vicinity of Waxahachie, Texas.. Its planned ring circumference was 87.1 kilometers (54.1 mi) with an energy of 20 TeV per proton and was designed to be the world's largest and most energetic particle accelerator. The laboratory …

A linear particle accelerator (often shortened to linac) is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline.The principles for such machines were proposed by Gustav Ising in 1924, while the first machine that worked was constructed by Rolf …

The following outline is provided as an overview of and topical guide to physics: . Physics – natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.

A list of particle accelerators used for particle physics experiments. Some early particle accelerators that more properly did nuclear physics, but existed prior to the separation of particle physics from that field, are also included.Although a modern accelerator complex usually has several stages of accelerators, only accelerators whose output has been used directly for …

A particle beam is a stream of charged or neutral particles.In particle accelerators, these particles can move with a velocity close to the speed of light.There is a difference between the creation and control of charged particle beams and neutral particle beams, as only the first type can be manipulated to a sufficient extent by devices based on electromagnetism.

In particle physics, a generation or family is a division of the elementary particles.Between generations, particles differ by their flavour quantum number and mass, but their electric and strong interactions are identical.. There are three generations according to the Standard Model of particle physics. Each generation contains two types of leptons and two types of quarks.

In physics, action is a scalar quantity describing how a physical system has changed over time. [clarification needed] Action is significant because the equations of motion of the system can be derived through the principle of stationary action.In the simple case of a single particle moving with a constant velocity (uniform linear motion), the action is the momentum of the particle …
