Abstract

The objective of Open Data is on one hand to produce trust in science and scientists among the general public. On the other hand to enable the reuse of data for further analyses and better exploitation. Open Data itself does not necessarily allow the reuse of data – to this end, resources (like e.g. storage and compute) as well as appropriate software and metadata are needed. PUNCH4NFDI, a consortium in the German National Research Data Infrastructure (NFDI), develops a Science Data Platform which integrates several resources and services necessary for the reuse of data from astronomy, astrophysics, astroparticle physics, particle physics, hadron and nuclear physics. To this end, the consortium builds wherever possible on the experience, existing services and tools of the different scientific communities and extends these or develops overarching layers wherever necessary. In this demo we show how different elements of the Science Data Platform, provided and in parts also developed by PUNCH4NFDI partner institutions in Germany, can be used by means of one example of a joint particle physics analysis of ATLAS and CMS Open Data. The workflow is submitted via the workflow engine ReAna, executed on Compute4PUNCH (federated compute resources), and reads the data, which was previously transformed to a common format, from Storage4PUNCH (federated storage resources).

Back-up information on the use case 9 The description is available (under PUNCH-AAI) via: https://gitlab-p4n.aip.de/punch/usecase_demonstrators/hep_higgsto4l_punch/ including all necessary files to run the workflow on REANA. Several levels of complexity are available. Data: - CMS open data from 2010, 2011 and 2012 - ATLAS open data (this version still using educational data) from 2012, converted to nTuples => the data for this use case is stored on Storage4PUNCH and available under PUNCH-AAI (data publication in preparation) - update to ATLAS data on research level ongoing Software: - written by DESY summer students, same code applied to ATLAS and CMS data (software publication in preparation) Reproduce with REANA: REANA instance at AIP, not yet fully integrated into PUNCH-AAI (i.e. registration for PUNCH-AAI and REANA instance necessary, however using the same credentials) => for more information on REANA, visit presentation by T.
