摘要
Recent results concerning the light-cone gauge are reported. In particular we revisit the nonsinglet Altarelli-Parisi kernel in the leading-log approximation. Ultraviolet and infrared singularities are neatly disentangled thanks to the Mandelstam-Leibbrandt prescription in the vector propagator. A new interpretation emerges of ''real'' and ''virtual'' diagram contributions. Then we exhibit the one-loop renormalization of the composite operator A(mu)a(0)A(nu)b(0) as a first step towards full control of gauge-dependent insertions.
