Geant4 QGSP_BERT_HP hadronic model

• QGSP_BERT and QGSP_BERT_EMV (see and recommending physics lists)
  Like QGSP, but using Geant4 Bertini cascade for primary protons, neutrons, pions and Kaons below ~10GeV. In comparison to experimental data we find improved agreement to data compared to QGSP which uses the low energy parameterised (LEP) model for all particles at these energies. The Bertini model produces more secondary neutrons and protons than the LEP model, yielding a better agreement to experimental data.

  QGSP_BERT_EMV is like QGSP_BERT, but parameters of electromagnetic processes tuned to yield better cpu performance with only slightly less precision.

  Both QGSP_BERT and QGSP_BERT_EMV are less CPU performant as QGSP.

• QGSP_BERT_HP
  This list is similar to QGSP_BERT and in addition uses the data driven high precision neutron package (NeutronHP) to transport neutrons below 20 MeV down to thermal energies.
