Quark-antiquark potential in QCD

Description

The potential energy of colour sources as a function of their separation is computed up to two loops; the renormalization group equations it satisfies are derived. This enables the author to obtain β(g) to O(g5) and recover its known value. The solution of this Callan-Symanzik equation to O(g5) leads to a colour-confining potential. A qualitative argument is given to reject it as an artifact of the approximation used. (Auth.)
