Abstract: A key ingredient in the description of double parton distributions is their scale dependence. If the colour of each individual parton is summed over, the distributions evolve with the same DGLAP kernels as ordinary parton distributions. This is no longer true if the two partons are correlated in their colour. We compute the relevant kernels for this case at next-to-leading order in the strong coupling.
