Parity

Physics; Particle physics

If a process is equally probable when the coordinates of space are reflected (as in a mirror), it is said to have parity symmetry.

Superparticle

Physics; Particle physics

Supersymmetry predicts the existence of superpartners of the Standard Model particles. These new types of particles, the superparticles, would represent a new quantum dimension.

Supersymmetry

Physics; Particle physics

A hypothetical symmetry relating particles of different spins. Under this symmetry, matter particles (spin one-half fermions) are related to force particles (spin-zero or spin-one bosons).

Superstrings

Physics; Particle physics

When supersymmetry is imposed on string theory, it becomes, superstring theory. The fundamental constituents of this theory are known as superstrings.

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 ...

Spin

Physics; Particle physics

A number that labels the intrinsic angular momentum of a particle, essentially how much the particle rotates around its axis. This number can only take on discrete values. Particles with different ...

String theory

Physics; Particle physics

A theory that seeks to incorporate a quantum theory of gravity into the Standard Model. In this theory, the fundamental constituents of matter are not particles, but strings. The particles that are ...
