Modeling Double Parton Scattering at LHC

We examine present data for double parton scattering at LHC and discuss theirenergy dependence from its earliest measurements at the Intersecting StorageRings (ISR). Different models for the effective cross-section are considered andtheir behavior studied for a variety of selected final states. We point out thatdata for pp → 4 jets or pp → quarkonium pair indicate σ ef f to increase withenergy. We compare this set of data with different models, including oneinspired by our soft gluon resummation model for the impact parameterdistribution of partons.
