The joint study of Double Parton Scatterings, in high energy proton-proton\nand proton-nucleus collisions, can provide a lot of information on multi-parton\ncorrelations. The multi-parton structure is in fact probed in a different way\nby DPS, in p-p and in p-A collisions. In p-A collisions the\ninterpretation of the experimental results may be however complicated by the\npresence of interference terms, which are missing in p-p. A suitable\nreaction channel, where interference terms are absent, is WJJ production. By\nstudying WJJ production in p-Pb collisions, we estimate that the fraction\nof events due to DPS may be larger by a factor 3 or 4, as compared to p-p,\nwhile the amount of the increased fraction can give a direct indication on the\nimportance of different correlation terms.\n
