Biography and Interests

Project

I am conducting validation studies on pileup simulation performance with CMS with Matthew Herndon at University of Wisconsin-Madison and Kevin Pedro at Fermilab. Currently, pileup events are created using FullSim and are added to signal events later using a process known as “pre-mixing.” This requires large amounts of storage for the pileup events until they are used for simulation, and as we move towards the High Luminosity LHC we need to explore alternatives to this procedure to save on storage space, among other crucial improvements.

Our goal with this study is to validate mixing FullSim signal events with FastSim pileup events, allowing pileup to be generated on-the-fly. This would eliminate the need for any pileup event storage entirely. Accurate simulation of pileup within CMS events is crucial, so this alternative needs to be checked against the current procedure, which has already been thoroughly studied to ensure physical accuracy. For this study, I focus on the validation of hits in the muon system using both MUO tag & probe and the muon DPG (detector performance group) ntuples to compare standard and hybrid mixing procedures.
