Full event interpretation with machine-learning-based particle-flow reconstruction in the CMS detector

Aram Hayrapetyan, Vladimir Makarenko, A. Tumasyan, W. Adam et autres

Abstract The particle-flow (PF) algorithm constructs a global description of each particle collision by producing a comprehensive list of final-state particles, and is central to event reconstruction in the CMS experiment at the CERN LHC. The existing PF implementation relies on physics-motivated …
