In theoretical physics, Seiberg–Witten theory is an = supersymmetric gauge theory with an exact low-energy effective action (for massless degrees of freedom), of which the kinetic part coincides with the Kähler potential of the moduli space of vacua.
The Wess–Zumino gauge (a prescription for supersymmetric gauge fixing) provides a successful solution to this problem. Once such suitable gauge is obtained, the dynamics of the SUSY gauge theory work as follows: we seek a Lagrangian that is invariant under the Super-gauge transformations (these transformations are an important tool needed to ...
In theoretical physics, a quiver diagram is a graph representing the matter content of a gauge theory that describes D-branes on orbifolds. Quiver diagrams may also be used to described N = 2 {\displaystyle {\mathcal {N}}=2} supersymmetric gauge theories in four dimensions.
In many supersymmetric extensions of the Standard Model, such as the Minimal Supersymmetric Standard Model, there is a heavy stable particle (such as the neutralino) which could serve as a weakly interacting massive particle (WIMP) dark matter candidate. The existence of a supersymmetric dark matter candidate is related closely to R-parity ...
Moduli spaces of supersymmetric gauge theories [ edit ] In general quantum field theories, even if the classical potential energy is minimized over a large set of possible expectation values, once quantum corrections are included it is generically the case that nearly all of these configurations cease to minimize the energy.
In supersymmetry theories of particle physics, a gaugino is the hypothetical fermionic supersymmetric field quantum (superpartner) of a gauge field, as predicted by gauge theory combined with supersymmetry. All gauginos have a spin of 1/2, except for the gravitino, which has a spin of 3/2.
In supersymmetry, 4D = global supersymmetry is the theory of global supersymmetry in four dimensions with a single supercharge.It consists of an arbitrary number of chiral and vector supermultiplets whose possible interactions are strongly constrained by supersymmetry, with the theory primarily fixed by three functions: the Kähler potential, the superpotential, and the gauge kinetic matrix.
Green and Schwarz realized that one can add a so-called Chern–Simons term to the classical action, having the form =, where the integral is over the 10 dimensions, is the rank-two Kalb–Ramond field, and is a gauge invariant combination of , , (with space-time indices not contracted), which is precisely one of the factors appearing in the ...
