shortdescription: A fast analysis format for/from edm4hep data will be created

description: >
The Future Circular Collider (FCC) is a proposed large-scale project at CERN that aims
to conduct detailed studies of the Higgs boson and its interactions, search for new particles,
new forces and possible dark matter candidates. With substantial gains in precision and
sensitivity, it would enable measurements beyond the reach of current colliders, including
the Large Hadron Collider (LHC) and its high-luminosity upgrade.
The FCC community, including studies of the FCC-ee design, uses EDM4hep and associated
software to describe the data model for ongoing simulation studies. EDM4hep defines a
series of C++ classes representing detector and physics objects corresponding to each
aspect of the simulation and event reconstruction pipeline. While important for detailed
studies, these data structures are inefficient for data analysis users who instead would
benefit from having fast to analyze columnar data. As FCC-ee aims to collect more than a
trillion Z-boson decays, speed of analysis codes is particularly important.
The scale of the FCC-ee physics program presents a significant computing challenge. Given
the projected collection of more than 10^12 Z-boson decays, analysis workflows must process
very large numbers of events efficiently. Compact columnar formats could help improve
analysis performance and reduce the time required to obtain physics results.
