Good question, no the energy levels (the n’s) are discretized. There is in fact an infinite number of states (at least the theory predicts this). In principle, as we gain more statistics and as we increase the collision energy we should always see new mesons being created.

If we do not than this would mean something beyond the standard model is occurring (and this would be something very interesting!!!!); which is why we continue to look for new mesons.

I.e. is (3P) the highest before the meson falls apart?

Oops that was a typo! Thanks for catching it.

Best,

I don’t really get this point:
> So basically for each value of n you have three unique particles!
Why three?

Thanks.
