• Extended supersymmetry — In theoretical physics, extended supersymmetry is supersymmetry whose infinitesimal generators Q i^alpha carry not only a spinor index alpha, but also an additional index i=1,2 dots mathcal{N} where mathcal{N} is integer (such as 2 or 4).Extended …   Wikipedia

• Supersymmetry — In particle physics, supersymmetry (often abbreviated SUSY) is a symmetry that relates elementary particles of one spin to another particle that differs by half a unit of spin and are known as superpartners. In other words, in a supersymmetric… …   Wikipedia

• Supersymmetry algebra — In theoretical physics, a supersymmetry algebra (or SUSY algebra) is a symmetry algebra incorporating supersymmetry, a relation between bosons and fermions. In a supersymmetric world, every boson would have a partner fermion of equal rest… …   Wikipedia

• Supersymmetry nonrenormalization theorems — In theoretical physics a nonrenormalization theorem is a limitation on how a certain quantity in the classical description of a quantum field theory may be modified by renormalization in the full quantum theory. Renormalization theorems are… …   Wikipedia

• Superspace — has had two meanings in physics. The word was first used by John Wheeler to describe the configuration space of general relativity; for example, this usage may be seen in his famous 1973 textbook Gravitation .The second meaning refers to the… …   Wikipedia

• Superpartner — In particle physics, a superpartner is a particle related to a more standard particle by supersymmetry. In this physical theory, it is proposed that every fermion should have a partner boson (the fermion s superpartner), and vice versa. Exact… …   Wikipedia

• Central charge — In theoretical physics, a central charge is an operator Z that commutes with all the other symmetry operators. The adjective central refers to the center of the symmetry group the subgroup of elements that commute with all other elements of the… …   Wikipedia

• R-symmetry — In theoretical physics, the R symmetry is the symmetry transforming different supercharges in a theory with supersymmetry into each other. In the simplest case of the N=1 supersymmetry, such an R symmetry is isomorphic to a U(1) group or its… …   Wikipedia

• Conformal field theory — A conformal field theory (CFT) is a quantum field theory (or statistical mechanics model at the critical point) that is invariant under conformal transformations. Conformal field theory is often studied in two dimensions where there is an… …   Wikipedia
