Awesome coffea

[nsmith-]

A place to collect publicly available examples of physics analyses in CMS or beyond using Coffea!

• boostedhiggs, with many derivatives (HIG-21-012, ...)
• TopCoffea (TOP-22-006)

Many examples can be found through github search: https://github.com/search?q=%22import+coffea%22+%28language%3A%22Python%22+OR+language%3A%22Jupyter+Notebook%22%29&type=code&l=Jupyter+Notebook

We have an Analysis Grand Challenge implementation making use of coffea here: iris-hep/analysis-grand-challenge (no physics publications as this is a technical exercise).

B2G analysis searching for ttbar resonances in dileptonic state is available on GitLab: https://gitlab.cern.ch/gagarwal/ttbardileptonic
This repository is a work in progress as of today.

Measurement of B hadron production fraction ratios using the CMS 2018 B parking data set: https://github.com/DryRun/boffea

CMS hadron calorimeter (HCAL) raw data analysis framework for Prompt Feedback Group (PFG): https://github.com/DryRun/hcalanalysis
(Implements a trivial schema and uses processors, but doesn't really use any coffea physics object methods)

https://github.com/bu-cms/bucoffea @AndreasAlbert but it hasn't seen any activity since ~2021. I'm not sure how things have evolved.

@lgray bucoffea was used for at least two analyses:

• Run-2 CMS monojet / mono-V
• Run-2 CMS VBF H(inv)

I left physics after these analyses, so don't know what happened after. @alpakpinar might know more.

@lgray @AndreasAlbert there is more recent activity in my fork of the repository - especially this branch is used for a version of the VBF H(inv) analysis mentioned above, using a ParticleNet tagger (under development at the moment & not very active).

Also I can add that the JetMET trigger group is using this tool to make it one of the standard ways to measure trigger efficiencies from NanoAOD (current effort mostly by @theochatzis and me). This repository can be found here.

https://github.com/yhaddad/NUCoffea @yhaddad but it's also not really had commits since 2021. Would be good to see where it's gone!

@lgray, this repo was used for EXO-19-003, and it has been on hold for quite some time, but various forks are still active and used mostly in DiHiggs and EXO. We have a new implementation quite similar to boostedhiggs used in SMP-23-001.

[lgray]

@yhaddad for the new implementation if it's available could you link it?
