Multiple Parton Interactions in Z+4j, W\pm W\pm +0/2j and W+ W- +2j production at the LHC

Understand

The expected rate for Multiple Parton Interactions (MPI) at the LHC is large.

• This requires an estimate of their impact on all measurement foreseen at the LHC.
• Conversely it provides new means of studying MPI at the LHC.
• In this paper we examine the role of MPI at the LHC, with the design energy of 14 TeV, in - Z production in association with four jets, - W\pm W\pm in association with zero or two jets.
