Anomaly Detection for Automated Data Quality Monitoring in the CMS Detector Open
Successful operation of large particle detectors like the Compact Muon Solenoid (CMS) at the CERN Large Hadron Collider requires rapid, in-depth assessment of data quality. We introduce the ``AutoDQM'' system for Automated Data Quality Mon…

Observation of Top Quark Pairs Produced in Association with a W or Z Boson in PP Collisions at the LHC Open
A measurement of top quark pairs produced in association with a W or Z boson is presented, using 19.5 fb-1 of proton-proton collisions with a center-of-mass energy of 8 TeV, collected by the CMS experiment at the LHC. Novel event reconstru…

Machine Learning Techniques in the CMS Search for Higgs Decays to Dimuons Open
With the accumulation of large collision datasets at a center-of-mass energy of 13 TeV, the LHC experiments can search for rare processes, where the extraction of signal events from the copious Standard Model backgrounds poses an enormous …

Boosted Decision Trees in the Level-1 Muon Endcap Trigger at CMS Open
The first implementation of a Machine Learning Algorithm inside a Level-1 trigger system at the LHC is presented. The Endcap Muon Track Finder (EMTF) at CMS uses Boosted Decision Trees (BDTs) to infer the momentum of muons in the forward r…

Boosted Decision Trees in the CMS Level-1 Endcap Muon Trigger Open
The first implementation of Boosted Decision Trees (BDTs) inside a Level-1 trigger system at the LHC is presented. The Endcap Muon Track Finder (EMTF) at CMS uses BDTs to infer the momentum of muons in the forward region of the detector, b…

Beam test evaluation of electromagnetic calorimeter modules made from proton-damaged PbWO<sub>4</sub>crystals Open
The performance of electromagnetic calorimeter modules made of proton-irradiated PbWO4 crystals has been studied in beam tests. The modules, similar to those used in the Endcaps of the CMS electromagnetic calorimeter (ECAL), were formed fr…
