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 …

Search for a narrow resonance with a mass between 10 and 70 GeV decaying to a pair of photons in proton-proton collisions at s = 13 TeV

A. Hayrapetyan, В. Макаренко, A. Tumasyan, W. Adam et autres

The existence of a new spin-zero particle with a mass below the electroweak scale is predicted by several theoretical models. Searches for resonant production of photon pairs at the LHC are able to probe these models. We present a search for a …
