Description
A short review of phenomenological models of Multiple Parton
Interactions (MPI) implemented in the three main Monte Carlo generators:
Herwig, Pythia, and Sherpa will be given. New observables which are
sensitive to different mechanisms of mini-jet production and MPI physics
will be introduced. The observables measure how the transverse momenta
of hadrons produced in association with various trigger objects are
balanced against it as a function of rapidity. It will be demonstrated
that the Monte Carlo generators show significantly different predictions
for the proposed observables. Finally, a measurement of the proposed
rapidity correlations performed by the CMS Collaboration will be discussed
