Abstract: Open data offers new possibilities for a wider audience to access, reproduce and complement active research. In high-energy particle physics many challenges arise, due to several different data formats and large data samples. Therefore, a transformation of the open data to a common data format is used. This enables analysis to be performed within a single workflow and reduces the amount of data and computation time by two orders of magnitude.Here we present an anlysis demonstrator developed in the context of the PUNCH4NFDI consortium showcasing the feasibility of analyzing Open Data from CMS and ATLAS at the same time. Further an example utilizing data from multiple CMS runs will be presented. The demonstrator uses the H → 4ℓ channel and features various levels of complexity to cater to a wide range of users. This framework guides users from basic visualization of the four-lepton invariant mass spectra to producing the four-lepton invariant mass spectrum from transformed datasets within hours.The talk will showcase the latest results of the analysis demonstrator, which may be used as an access point for future open data analysis.
