Coupling constants run with the logarithm of energy.(adsbygoogle = window.adsbygoogle || []).push({});

This is a result of renormalization, its equations, and the

change of the effect of the virtual particle cloud with energy.

Is there a simple way to understand why this happens with the

log of energy, instead of with another function?

Logarithm is the integral of 1 over r; does this enter somehow?
