The abstract, sentence by sentence
We review the effect of scale evolution on a number of different correlations in double parton scattering (DPS). The strength of the correlations generally decreases with the scale but at a rate which greatly varies between different types. Through studies of the evolution, an understanding of which correlations can be of experimental relevance in different processes and kinematical regions is obtained.

The paper
Original abstract
We review the effect of scale evolution on a number of different correlations in double parton scattering (DPS). The strength of the correlations generally decreases with the scale but at a rate which greatly varies between different types. Through studies of the evolution, an understanding of which correlations can be of experimental relevance in different processes and kinematical regions is obtained.

For the unpolarized DPDs we take a simple factorizing ansatz at the starting scale ($Q_0^2 = 1 ^2$), [equation] The single parton densities used will be either of the two LO sets MSTW 2008 [ref] and GJR 08 [ref] .

Two versions of this have been discussed in the literature: a homogeneous equation describing the separate evolution of each of the two partons and an inhomogeneous including also the splitting of one parent parton into the two partons that undergo hard scattering [ref] .
