Description
Pileup modelling is an integral part in the data simulation and the downstream experimental analyses. Traditionally this is done by digitising the simulated pile up (PU) hits which are overlaid on digitised Hard Scatter (HS) hits, before reconstruction. A faster alternative is to reconstruct the PU separately and overlay them on HS tracks - i.e. overlay is done at the reconstruction level. This work presents a technique to identify regions where one can do the overlay without significant performance losses downstream, and provides a template for combining the two approaches for optimal speed and efficiency.
