Particle physics

A property of quarks and gluons. Gluons can exchange color between quarks and other gluons. This process is the origin of the strong force. It has nothing to do with the color perceived by the human ...

cosmic rays

Physics; Particle physics

Any of the particles from outer space that are continuously colliding with the Earth's atmosphere. They are mostly protons, with some nuclei, electrons, and photons. Their interactions with the ...

coupling constant

Physics; Particle physics

The parameter that describes the strength of a given force.

quantum mechanics

Physics; Particle physics

In microscopic systems, particles such as electrons and protons behave like waves. Quantum mechanics replaces the more familiar Newtonian mechanics to describe such phenomena.

quantum numbers

Physics; Particle physics

The name given to the labels that describe various characteristics of elementary particles, atoms and molecules. Examples include the charge and spin of a particle.

quark

Physics; Particle physics

One of the fundamental constituents of matter. These particles posses spin ?. They come in six flavors: up (u), down (d), strange (s), charm (c), bottom (b), and top (t). Only the up and down quarks ...
