CEDAR is MCnet’s initiative to support sustainable, reusable software tools for collider phenomenology, including Rivet, YODA, and LHAPDF, enabling precision comparisons between theory and experiment.
LHAPDF (The Les Houches Accord PDFs) is a standardised library for accessing parton distribution functions (PDFs) in high-energy physics. It provides a common interface to a wide range of PDF sets, enabling consistent and reproducible predictions in collider simulations and analyses.
Rivet is a toolkit for validation and analysis of Monte Carlo event generators in particle physics. It provides a library of reusable analysis components and a large collection of published analyses, enabling precise, reproducible comparisons between theory and experimental data.
YODA is a lightweight C++ and Python library for histogramming and statistical analysis, designed for use in particle physics workflows. It supports reproducible, high-performance data analysis and is the foundation for data handling in tools like Rivet.
