Description
Using the gradient flow, the strong coupling constant alpha_s and the vacuum angle theta of the SU(3) Yang-Mills theory are investigated in the infrared limit. It appears that theta tends to zero (mod 2 pi), thus restoring CP invariance, while alpha_s shows power-law divergence, which naturally leads to a linear confining potential.
