Detailed Description

Data management for Standard Model particle classifications.

This class represents "per-problem" shared data about standard model particles being used.

The ParticleParams is constructed on the host with a vector that combines metadata (used for debugging output and interfacing with physics setup) and data (used for on-device transport). Each entry in the construction is assigned a unique ParticleId used for runtime access. See celeritas::PDGNumber for details on the PDG code used during construction.

Member Function Documentation

device_ref()

DeviceRef const & celeritas::ParticleParams::device_ref ( ) const

inlinefinalvirtual

Access material properties on the device.

Implements celeritas::ParamsDataInterface< ParticleParamsData >.

find()

ParticleId celeritas::ParticleParams::find ( PDGNumber  pdg_code ) const

inline

Find the ID from a PDG code.

Todo:

Multiple particles can share a "generic" PDG code so this should be a multimap.

host_ref()

HostRef const & celeritas::ParticleParams::host_ref ( ) const

inlinefinalvirtual

Access material properties on the host.

Implements celeritas::ParamsDataInterface< ParticleParamsData >.
