Industry: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 spins will interact in different ways. Electrons have spin ?, while photons have spin one.
Industry:Physics
The hypothetical spin-zero superpartner of the quark.
Industry: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 observed are manifestations of the vibrations of fundamental strings.
Industry:Physics
When a star exhausts its nuclear fuel, it under goes a catastrophic collapse. The resulting explosion is known as a supernova. It often is brighter than an entire galaxy.
Industry: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.

see superparticle.
Industry: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).
Industry:Physics
When supersymmetry is imposed on string theory, it becomes, superstring theory. The fundamental constituents of this theory are known as superstrings.
Industry:Physics
Physicists use symmetries to restrict possible theories of fundamental particles. As an analogy, consider the human face. If you were able to see only the right side of a person's face, you would still be able to guess what the other side of the face looks like, because of the symmetry that our bodies possess. The other side of the face cannot look like just anything, you know what it looks like-because of symmetry. Similarly, symmetries observed in nature limit what theories look like.
