Development of systematic uncertainty-aware neural network trainings for binned-likelihood analyses at the LHC / CMS Collaboration
We propose a neural network training method capable of accounting for the effects of systematic variations of the data model in the training process and describe its extension towards neural network multiclass classification. [...]

System testing of the CMS Endcap MIP Timing Layer / Fernández Madrazo, Celia (Boston U.) /CMS Collaboration
The high luminosity phase of the LHC (HL-LHC) opens up new windows for exciting discoveries but also brings about new challenges due to the high pileup environment of approximately 200 simultaneous interactions per collision. Precise measurements of track and vertex timing can efficiently mitigate these pileup effects. [...]
