Fine-tuned Normalizing Flows for ALICE Zero Degree Calorimeter Fast Simulation

Emilia Majerz, Jacek Otwinowski, Witold Dzwinel +1

Simulating the ALICE Zero Degree Calorimeter (ZDC) neutron detector responses at the LHC is computationally expensive, requiring complex Monte Carlo chains. We develop a generative…
