CP3 is coordinating and leading the development of the MadGraph suite of tools. Tools use for the simulation of High-Energy Physics collision.
This project includes:
- NLO computation
- MadNIS: Neural Importance Sampler (AI for the phase-space integration)
- HardWare: How to port the code on modern facility (GPU, quantum computer, ...)
