Description
Future collider performance will be increasingly shaped by the complex dynamics at the interaction point (IP). Indeed, proposed and existing machines operate in regimes of unprecedented luminosity and beam-beam parameters. This demands high-fidelity and flexible modeling tools.
A key challenge is the development of simulation frameworks that remain reliable across diverse interaction regimes, including SuperKEKB, EIC, FCC-ee, muon colliders, gamma–gamma colliders, and advanced concepts such as wakefield-based accelerators. In this context, we present recent advancements in WarpX, a particle-in-cell code capable of modeling beam-beam interactions at the IP. We describe new developments, enhanced physics capabilities, and ongoing efforts to broaden accessibility to a wider user community.
We also discuss open challenges and present initial work toward a unified simulation pipeline that enables end-to-end modeling from beam dynamics to collision. Specifically, we couple the BLAST codes ImpactX (for long-term beam dynamics) and WarpX (for detailed IP physics).
Finally, we showcase visualizations of beam-beam simulations developed by four high school students as part of the Experiences in Research program at LBNL.
