- 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
- 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"
- 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
- 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
- Confusion about commutator between $R$-symmetry and supercharges in SUSY
This is what it means to be linear operator A map from a vector space to another (in this case the same vector space) The "definition" of R symmetry acting on supercharges acting is made in a classical field theory (in super space) Promoting this classical field theory to a quantum field theory involves computing the Dirac braket in the standard fashion and promoting it to a (anti
- Why does the SUSY algebra only close off-shell?
This suggests that the SUSY algebra only closes on-shell However, since the action is supersymmetric invariant (even off-shell !), $$ \delta_ {\epsilon} S = 0 \implies \ { \delta_ {\epsilon_1}, \delta_ {\epsilon_2} \} S = 0 $$ The operation $ \ { \delta_ {\epsilon_1}, \delta_ {\epsilon_2} \}$ is bosonic, and the last equation is the definition
- How can the mass of Higgs give preference to SUSY vs multiverse?
According to the documentary Particle Fever, the precise value of the Higgs boson's mass could give more credence to either SUSY or multiverse theories If the mass had been 115 GeV or below SUSY w
- 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)
