- Mathematically: What is SUSY? - Physics Stack Exchange
Wikipedia says: In particle physics, supersymmetry (often abbreviated SUSY) is a symmetry that relates elementary particles of one spin to other particles that differ by half a unit of spin and are
- cal N}=4$ supersymmetric yang-mills theory and S-duality
What is the action for $ {\cal N}=4$ SUSY Yang-Mills and what is the physics of the various terms in the action? B Give a simple explanation for the origin of Montonen-Olive duality in this theory
- What if the LHC doesnt see SUSY? - Physics Stack Exchange
Obviously, if SUSY is there at the LHC scale, the LHC will eventually be discovering fireworks of new effects (SUSY is also the most attractive realistic possibility for the experimenters) - all the superpartners of the known particles, among other things (such as an extended Higgs sector relatively to the Standard Model)
- What is $R$-symmetry with supersymmetric theory?
To be precise (I just saw this post), without really complicating the discussion: the R-symmetry is the largest subgroup of the automorphisms group of the supersymmetry algebra which commutes with the Lorentz group In simple words, there exists a group which commutes with the Lorentz group AND leaves the susy algebra (the anticommutators) invariant The largest such group is referred to as R
- Difference between $\\mathcal{N}=2$ and $\\mathcal{N}=(1,1)$ SUSY
I think I figured out the meaning of this after some research so, I am posting an answer to my own question The answer is there is nothing called $\mathcal {N}= (1,1)$ superalgebra The superalgebra is always named by $\mathcal {N}$ with integers The $\mathcal {N}= (1,1)$ actually means a supergravity multiplet so my original question was wrong We get this multiplet as the massless level of
- Why is the R-symmetry in $\\mathcal{N}=4$ $SU(4)$ and not $U(4)$?
But $\mathcal {N}=4$ is a SCFT, and the R-charge appears in the SUSY algebra on the r h s of the anticommutators $\ {S,Q\}$ and cannot be anomalous without breaking SCFT
- Book with solved examples and exercise problems for SUSY
4 Supergravity by Daniel Z Freedman and Antoine Van Proeyen is quite excellent for illustrating Clifford algebra techniques and calculations in the classical SUSY SUGRA in general (in the component formalism) The book has several calculations illustrated and plenty of exercises
- quantum field theory - Terminology about chiral supermultiplet and . . .
However, SUSY representations furnish reducible Poincaré representations, so supermultiplets in general correspond to multiple particles having the same mass, which are related by supersymmetry transforms In this context, the broader term "multiplet" is used interchangeably with "supermultiplet"
