Why is QCD non-perturbative at low energies?
In QCD isn't the expansion parameter the fine structure constant?
[tex] \alpha_s \approx \frac{1}{137} [/tex]
Does this somehow depend on energy, which wouldn't make sense to me. I cannot seem to find a good answer anywhere, so I thought I would ask here.
Thanks.
