Dynamical supersymmetry breaking and Witten index
Witten index, defined as ${\rm Tr}(-1)^F$, makes know if supersymmetry is spontaneously broken or not for a given model. But it is known that supersymmetry can be also broken dynamically and one can ...

In SUSY why does electroweak symmetry breaking only happen in the SM sector?
This is a difficult question to phrase succinctly, so I hope the title makes sense. What I want to understand is what seems like a lack of symmetry (besides SUSY-breaking) between the SM sector and ...

Where does the hidden supersymmetric sector of the MSSM come from?
At the end of Chapter 14 of the "Supersymmetry Demystified book" from Patrick Labelle it is mentioned that to constrain the number of allowed softly SUSY breaking terms, a shadow or hidden ...

Which is the coupling between the photon and the SU(2)xU(1) gauginos, before symmetry breaking?
The photon field is the non chiral piece of SU(2)xU(1), independently of symmetry breaking or not, isn't it?
But before symmetry breaking, each gauge boson has only a chiral gaugino as ...
