Multiple Partonic Interaction Developments in Herwig

We briefly review the status of the multiple partonic interaction model in the Herwig++ event generator. First, we show how a change in the colour structure of an event in Herwig++ results in a significant improvement in the description of soft inclusive observables in \(pp\) interactions at \(\sqrt...

Description
Summary:We briefly review the status of the multiple partonic interaction model in the Herwig++ event generator. First, we show how a change in the colour structure of an event in Herwig++ results in a significant improvement in the description of soft inclusive observables in \(pp\) interactions at \(\sqrt{s}=900\) GeV. Then we present a comparison of some model results to ATLAS Underlying Event data at \(\sqrt{s}=7\) TeV.
