Abstract

We calculate ccˉccˉc\bar{c}c\bar{c} and bbˉbbˉb\bar{b}b\bar{b} production cross section in Double Parton Scattering (DPS) processes at the energies of LHC. In our calculation we include saturation effects in the gluon distribution. For charm production, our results confirm the prediction of a previous work in which saturation effects were neglected, namely that at the energies of LHC charm production in DPS processes becomes comparable with charm production in SPS. We also estimate the production of ccˉbbˉc\bar{c}b\bar{b} in DPS. Our results indicate that at s=14\sqrt{s}=14 TeV half of the total amount of bottom produced in proton-proton collisions comes from this process.
