What is actually being conserved? I've calculated it for the Wess-Zumino model but I still have no idea what is actually being conserved due to Noether's Theorem.

There is already a similar question, but the answers don't actually say if there is anything physically conserved.

I have heard that the number of fermions is kept equal to the number of bosons, but is this not a fact that susy requires? I feel like it doesn't actually come from the charge itself.

In Qmechanic's answer it is said that "the experimental consequences of a conserved supercharge are extracted by other indirect means." What are these means?

  • $\begingroup$ Supercharge is what is conserved. The question should be I guess "What does supercharge represent physically?". $\endgroup$ Jun 18, 2019 at 15:49
  • $\begingroup$ It is a formal entity conserved by quantum motion. "Physically"? You mean you want an intuitive metaphor for it? You are happy with the "physical" intuition on the Runge-Lenz vector? It is all in the math, I fear. Unbroken supercharges do pair up fermions and bosons of a given mass, so you heard right. Intros to SUSY prove that at the very start. $\endgroup$ Jun 18, 2019 at 16:07
