Description
Bandwidth and storage limitations are a major bottleneck for many physics measurements and searches in HEP. The CMS experiment has addressed this constraint with several techniques that increase the number of events saved to disk while preserving physics performance; these approaches are still evolving and will be improved for Phase-2.
This talk will give an overview of the status of the compression techniques used in CMS with a focus on data scouting (reduced-content, trigger-level formats) and RAW Prime (strip cluster saved instead of strip raw data), and their impact on physics analyses. We will summarize how these methods enable higher effective trigger rates, lower thresholds, and larger datasets — particularly for low-mass and soft-object signatures — and outline ongoing developments for Run 3 and the HL-LHC.
