There definitely is a classical Lagrangian for those theories. It’s just that quantum effects are very important in the presence of confinement and SSB, not so much when everything’s perturbative.

But you can still yield real eigenvalue s using these types of operators or am I pigeonholing the term observerable too hard.
I honestly don't understand this field all too well .. i understand it when i'm talking to the non perturbative guy here at UCI, but i forget exactly how it's defined non perturbatively

I hear that, in parastatistics observables have at least two definitions which still trips me up tremendously. Probably just trying to latch onto one definition too hard. Thanks for the info tho it's cool to see operators like that. Things I usually dont think about!
