Beam-beam simulations for different future colliders

The design and optimization of future colliders – including Higgs factories, wakefield, and gamma-gamma colliders – require a detailed understanding of beam-beam effects at the interaction point. Here the physics is rich, consisting in nonlinear disruption, beamstrahlung, luminosity losses, and significant background generation. One of the key challenges is the development of up-to-date modeling tools that can be considered accurate and reliable even under this extreme regime of interaction. Here, we present recent advancements in WarpX, a particle-in-cell code that can model both the plasma-based acceleration stages and the interaction point. We detail the most recent code developments and efforts to provide a widespread user base. We show new simulation results for different types of colliders that address the role of beamstrahlung and secondary pair generation. These results can provide a baseline for next feasibility studies and conceptual designs of future colliders.
