It has a continuum limit.
It's completely well-defined.
As you know, it has very strange consequences in the IR.
In large distances, it confines.
You're not allowed to have free charged particles in QCD.
You have to have glue balls or protons, whatever.
So QCD is confining.
That means that it's called asymptotic freedom and infrared slavery.
So in the infrared, things get strongly coupled and you just can't pull out the individual gluons.
They're too strongly interacting.
Instead, the only kind of real physical excitation in QCD is a glue ball.
just made out of many gluons.
That's what people study in lattice-gauge theory.
This theory is similar.
It's very weakly coupled at short distances in the UV.
but at large distances, strongly coupled.
Still completely well-defined.
You can put this thing on a computer, and you could try to find what are the excitations.
What's the analog of a glue ball in this theory?
We haven't yet done that, but actually I have a student doing it.
