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…
Amplitude Surrogates for Multi-Jet Processes
Luca Beccatini, Fabio Maltoni, Olivier Mattelaer +1
Accurate and efficient amplitude predictions are essential for precision studies of multi-jet processes at the LHC. We introduce a novel neural network architecture that predicts m…
Automated event generation for S-wave quarkonium and leptonium production in NRQCD and NRQED
Alice Colpani Serri, Chris A. Flett, Jean-Philippe Lansberg +3
We present an extension of the MadGraph5_aMC@NLO framework that enables the automated calculation of leading-order cross sections for S-wave quarkonium and leptonium production wit…
Automated computation of spin-density matrices and quantum observables for collider physics
Valentin Durupt, Fabio Maltoni, Olivier Mattelaer
We present a fully automated framework to compute production spin-density matrices for generic collider processes at tree level within \textsc{MadGraph5\_aMC@NLO}. The method assem…
