Apache Arrow interface for PODIO

Arnav Dham

This project aimed to implement a new Apache Arrow backend for PODIO (Plain-Old-Data I/O), a C++ library designed for high-performance data modeling in particle physics. Over the summer, I added an in-memory Apache Arrow backend(Along with parquet writing and reading capability) to enable language-independent, columnar data access for flat and nested structures, improving throughput and enabling modern heterogeneous computing workflows.

Integration of CMS Combine with FCCAnalyses

Soumyadip Niyogi

This summer, as a Google Summer of Code contributor with the HEP Software Foundation at CERN, I am bridging the gap between FCCAnalyses and CMS Combine. My project aims to build a native Python interface that automates the generation of datacards and RooFit workspaces directly from RDataFrame histograms, streamlining the path from simulated events to physics results.
