Bound-state production in MadGraph5_aMC@NLO
Alice Colpani Serri, Chris A. Flett, Jean-Philippe Lansberg +3
I present the first implementation in MadGraph5_aMC@NLO for bound-state production, including quarkonium, leptonium, and B(c) mesons within Non-Relativistic Quantum Chromo-Dynamics…
MadSpin2: automated spin-entangled decays of heavy resonances via the spin-density matrix formalism
Spyros Argyropoulos, Valentin Durupt, Olivier Mattelaer
The simulation of processes that contain multiple particles from the decay of unstable resonances becomes computationally challenging both at leading order and beyond. This paper p…
MadSpace -- Event Generation for the Era of GPUs and ML
Theo Heimel, Olivier Mattelaer, Ramon Winterhalder
MadSpace is a new modular phase-space and event-generation library written in C++ with native GPU support via CUDA and HIP. It provides a unified compute-graph-based framework for…
