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

 The mixing procedure is done via the "PileUpMerger" module. The user can specify 4 parameters: PileUpFile, MeanPileUp, ZVertexWidth, ZVertexResolution.

 the event sample containing pile-up events in binary format. This format allows for faster random event access compared to root trees. Basic information about the event is contained (particle 4-momenta, vertex position, and Particle ID)

 This sample has to be generated in advance with an event generator (typically Pythia6/8 or HERWIG) and then converted into binary format.
 
-*MeanPileUp:
+* MeanPileUp:
 
 the 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.
 
-*ZVertexWidth:
+* ZVertexWidth:
 
 Pile-up events randomly populate the z-axis. The position of each pile-up event is generated from a gaussian distribution with a standard deviation ZveterxWidth.
 
-*ZVertexResolution
+* ZVertexResolution
 
 For |z|< ZVertexResolution the hard interaction vertex cannot be distinguished from pile-up vertices. For such pile-up events both charged and neutrals are then merged in the event (no charged particle subtraction).
