Particle physics
double beta decay
Physics; Particle physics
The process in which a neutron in a nucleus transforms into a proton by emitting an electron and an anti-neutrino is known as beta decay. When two neutrons undergo this transformation simultaneously, ...
electron
Physics; Particle physics
A fundamental constituent of matter. Along with protons and neutrons, electrons are the building blocks of atoms. They have negative electric charge.
electroweak symmetry breaking
Physics; Particle physics
Although electromagnetism and the weak force have the same strength at high energies, electromagnetism is much stronger than the weak force in our everyday experience. The process by which a single ...
electroweak unification
Physics; Particle physics
This theory describes two of the four fundamental forces, elctromagnetism and the weak interaction (responsible for nuclear decays) as a single force at high energy.
electron volt (eV)
Physics; Particle physics
A unit of energy equal to the amount kinetic energy an electron gains after being accelerated through an electric potential of 1 Volt. It can also be used as a unit of mass by applying Einstein's ...
femtobarn (fb)
Physics; Particle physics
10 -15 barns. A unit used to measure cross-section. The inverse of this unit is used to measure integrated luminosity.
fermion
Physics; Particle physics
The term for a particle with half-integer spin. Examples include the quarks and leptons of the Standard Model.
