Call for superselection rules [:]-)

[seratend]

Hi everybody,

I am looking for an exhaustive identification of the known quantum variables with superselection rules.

Here is at least some of the well know:
- particle mass (classical QM)
- particle electric charge (classical QM)
- particle spin

So, I hope that some of the people around here can add others to this list :rolleyes: .

Seratend.
