Efficient Multi-Jet Merging at High Multiplicities

Christian Preuss (Monash University)


I will present an implementation of the CKKW-L multi-jet merging technique to so-called sector showers as implemented in the Vincia antenna shower. The bijective nature of sector showers allows for efficient multi-jet merging at high multiplicities, as any given configuration possesses only a single shower history. After briefly reviewing the idea of sector showers, I will demonstrate that the complexity of constructing histories for these develops only an effective linear scaling with the number of final-state particles. Using the example of weak boson+jets at the LHC, I will demonstrate that the overall event generation time and the memory footprint of the new implementation remain approximately constant when including additional jets. This talk will be based on
