PALLAS Project - GEANT4 Collaboration This class defines a modular physics list for Geant4 simulations in the PALLAS project. It configures a combination of electromagnetic, hadronic, ion, and decay physics, using high-precision (HP) models where relevant for accurate plasma and nuclear interaction modeling.

Key features:

• Uses HP models for neutron elastic and inelastic scattering
• Includes EM Option3 physics for improved multiple scattering accuracy
• Registers radioactive decay physics for isotope handling
• Configures nuclide table thresholds for short-lived isotopes

Note

This physics list is optimized for applications involving plasma physics and detailed nuclear interactions.

< Handles particle decays < EM physics with high-accuracy multiple scattering < Extra EM processes (gamma-nuclear, synchrotron, etc.) < High-precision neutron elastic scattering Cross-section based hadron elastic scattering < Binary cascade + HP neutron physics < FTFP_BERT with HP neutron models < Liège intranuclear cascade Alternative inelastic hadronic physics < Ion elastic scattering < Ion inelastic physics using cross-section data < Ion inelastic physics using INCLXX model < Stopping of charged particles (e.g., muons)

Modular physics list for PALLAS simulations.

This class registers the set of physics processes used in the simulation. The configuration prioritizes high-precision neutron physics and detailed EM modeling for plasma and nuclear physics applications.

Example usage:

auto physicsList = new PlasmaMLPALLASPhysics();
runManager->SetUserInitialization(physicsList);
