Abstract
Processes with coloured particles in the initial state are
generally infrared divergent. We investigate the effect of this on
processes with colourless particles in the initial state, when the
amplitude is near an intermediate quark pole. The result is a
characteristic logarithmic depedence on the 'binding energy'(even
though spectator interactions are taken into account), and the
result is gauge-invariant. Summed to all orders the logarithms
could perhaps suppress the quark pole.
