Workflow Management with Snakemake: A Case Study in Tau Physics at the ATLAS Detector — •Luka Vomberg1, Christian Grefe2, Philip Bechtle1, and Klaus Desch1 — 1Physikalisches Institut, 53115 Bonn — 2CERN
Data analyses in particle physics often rely on complex software workflows. Reproducing and reusing such analyses is frequently challenging, as it is difficult to keep track of the many interdependent individual steps. This presentation illustrates, through a case study, how the workflow management tool Snakemake contributes to declaratively uniting all necessary steps into a comprehensive package.
The case study focuses on an analysis measuring the TauID efficiencies in Run 3 of the LHC at the ATLAS detector, which uses the ABCD method to estimate the contribution from misidentified tau-leptons. Various ATLAS software packages are integrated into the overall workflow, initially structured to fully reproduce the results of the equivalent Run 2 analysis and then adapted to the requirements of Run 3.
