After a brief introduction to the physics of soft gluons in QCD we present a surprising prediction. Dijet production in hadron-hadron collisions provides the paradigm, i.e. h(1) + h(1) -> jj + X. In particular, we look at the case where there is a restriction placed on the emission of any further jets in the region in between the primary (highest pT) dijets. Logarithms in the ratio of the jet scale to the veto scale call be summed to all orders in the strong coupling. Surprisingly, factorization of collinear emissions fails at scales above the veto scale and triggers the appearance of double logarithms in the hard sub-process. The effect appears first at fourth order relative to the leading order prediction and is subleading in the number of colours.
