    33Multiple particle interactions per bunch-crossing are now implemented in Delphes. The procedure is divided in two main parts:
    44
    5 * mixing pile-up events with the main interaction
    6 * pile-up subtraction with the fast jet area method
     5*mixing pile-up events with the main interaction
     6*pile-up subtraction with the fast jet area method

    88=== Mixing pile-up ===

    1616This sample has to be generated in advance with an event generator (typically Pythia6/8 or HERWIG) and then converted into binary format.

    2020the average amount of pile-up events per bunch-crossing. For each hard scattering, N pile-up events will be randomly chosen from the PileUp file, where N is a random number following Poisson statistics with a mean MeanPileUp.
