Abstract
A Wilson loop with light-like sides to order g4 contains quartic divergences, ε-4, in dimensional regularization with d = 4 - ε. We evaluate the leading ε-4 and first non-leading ε-3 divergences. The part proportional to C2 (R) obeys the exponentiation theorem. The leading non-Abelian C (R) C (G) divergences cancel out.
