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.
Why does the SUSY algebra only close off-shell?
Sep 29, 2024 · 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}, …
How can the mass of Higgs give preference to SUSY vs multiverse?
Nov 2, 2014 · 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 …
How does one determine the $R$-symmetry group?
Jun 13, 2020 · Properties of R-symmetry group depends on spinor structure: Here M means Maiorana spinors, MW - Maiorana-Weyl, S- symplectic. Spinor structure depends on dimension and signature …
Confusion about commutator between $R$-symmetry and …
Nov 2, 2024 · 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 …
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.
How can string theory work without supersymmetry?
If you spend some time looking in detail at the arguments that string theory requires supersymmetry, you'll find that they are not watertight. (How could they be, since we still can't say/don't know …
Spontaneous breaking of supersymmetry - Physics Stack Exchange
Jun 11, 2019 · Thus, if you have some non-trovial action of the susy generator as in (2), then the state will not be invariant under finite group transformations (but rather covariant). Also, note the …
What if the LHC doesn't 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 …
