Typedef Documentation

using ActsFatras::ChargedElectroMagneticPhysicsList = typedef PhysicsList<detail::StandardScattering, detail::StandardBetheBloch, detail::StandardBetheHeitler>

Electro-magnetic interactions for charged particles.

Scattering must come first so it is computed with the unmodified initial energy before energy loss is applied.

Warning
The list has no cuts on input particle charge or kinematics, i.e. it relies on the simulator to preselect relevant charged particles before application.
