Multiple parton interactions in Herwig++ — •Christian Röhr and Stefan Gieseke — Institut für Theoretische Physik, Karlsruher Institut für Technologie, Karlsruhe, Deutschland

Discoveries at the LHC are expected to occur in hard events, e.g. with high-pt jets/leptons or large missing energy. However, less hard scatters are also important to understand: Due to the high peak luminosity at the LHC, the triggered events are typically accompanied by a sizable number of (usually soft) pile-up events, i.e. further simultaneous proton collisions. This calls for valid soft-inclusive models in event generators. The event generator Herwig++ accesses this task using a model for multiple parton interactions. This talk covers new developments in this model.
