Description

BeAGLE (Benchmark eA Generator for Leptoproduction) is the primary event generator currently used to simulate deep inelastic scattering on nuclei (e+A) for the upcoming Electron-Ion Collider (EIC) in the U.S. It plays a central role in advancing our understanding of key nuclear physics processes, informing detector design, and guiding the integration requirements for interaction regions. As the principal simulation tool used by the ePIC collaboration, BeAGLE is expected to be pivotal for the physics case and engineering of the second IR. However, BeAGLE’s legacy FORTRAN codebase presents significant challenges for modern development, extensibility, and long-term support. To overcome these limitations, we have initiated a comprehensive rewrite of BeAGLE in C++, resulting in BeAGLE++, a modern, modular, and extensible event generator designed to meet the evolving demands of the EIC physics program.
In this talk, I will present the first release of BeAGLE++, highlighting its architectural improvements and enhanced physics capabilities. Particular focus will be given to simulations of particle production in the target fragmentation region, a key probe of final-state interactions and nuclear effects. BeAGLE++ will be essential for precision simulations, systematic studies, and data analysis workflows, providing the community with a robust and sustainable toolset ahead of EIC operations and marking a major step forward in lepton-nucleus collision modeling.
