| 136 | <B>Hadronic physics</B> |
---|
| 137 | <UL> |
---|
| 138 | <LI><U>Revised hadronic modeling, resulting in longer shower shapes</U>:<BR> |
---|
| 139 | the FTF model now has improved treatment of diffraction. As a result |
---|
| 140 | the longitudinal shower component now starts later and ends later, which |
---|
| 141 | goes in the direction of the data. The addition of quasi-elastic |
---|
| 142 | scattering (<TT>G4QuasiElasticChannel</TT>) to the QGS model is also |
---|
| 143 | expected to improve shower shapes by reducing the deep inelastic component.</LI> |
---|
| 144 | <LI><U>New cross section data sets added</U>:<BR> |
---|
| 145 | Barashenkov parameterised cross sections are now available for elastic |
---|
| 146 | and inelastic nucleon-nucleus and elastic and inelastic pion-nucleus |
---|
| 147 | scattering.</LI> |
---|
| 148 | <LI><U>Cross sections for user-defined elements</U>:<BR> |
---|
| 149 | cross sections are now calculated based on user-defined isotope |
---|
| 150 | abundances, if they are provided. Natural abundances are used |
---|
| 151 | otherwise.</LI> |
---|
| 152 | <LI><U>Improved muon capture model</U>:<BR> |
---|
| 153 | <TT>G4QCaptureAtRest</TT> model provides more accurate final state |
---|
| 154 | electron spectrum for muon capture and more accurate secondary hadron |
---|
| 155 | sprectra for hadron capture.</LI> |
---|
| 156 | <LI><U>Error reporting</U>:<BR> |
---|
| 157 | when a segmentation fault occurs in a hadronic process, the information |
---|
| 158 | about the process and model name where the fault has occurred will be |
---|
| 159 | printed out.</LI> |

---|
| 162 | <B>Physics Lists</B> |
---|
| 163 | <UL> |
---|
| 164 | <LI>FTFP and FTFC use a significantly revised FTF model. Comparisons to thin |
---|
| 165 | target experiment at ~10 <TT>GeV</TT> show much better agreement with data; |
---|
| 166 | the model is still under validation at higher energies. Prelimirary tests |
---|
| 167 | display slightly longer showers than the previous version of FTFP/FTFC.</LI> |
---|
| 168 | <LI>QGS type physics lists (QGSP, QGSC, QGSP_BERT, etc) now include a simple |
---|
| 169 | quasi-elastic model for a small fraction of high energy inelastic |
---|
| 170 | interactions. The cross-section parameterisations for inelastic |
---|
| 171 | interactions include the quasi-elastic cross-section, while QGS only |
---|
| 172 | models deep inelastic interactions. |
---|
| 173 | <UL> |
---|
| 174 | <LI>For comparison or backward compatibility, the new QGSP_NQE, |
---|
| 175 | QGSP_EMV_NEQ, and QGSP_BERT_NQE ignore this new quasi-elastic, |
---|
| 176 | and are therefore the equivalent of QGSP, QGSP_EMV, and QGSP_BERT |
---|
| 177 | available in release 8.2 and before.</LI> |
---|
| 178 | <LI>Also, the obsolete QGSP_LEAD/QGSP_LEAD_HP do not include |
---|
| 179 | quasi-elastic.</LI> |
---|
| 180 | </UL></LI> |
---|
| 181 | <LI>QGSC physics list and its variants use CHIPS <TT>G4QCaptureAtRest</TT> |
---|
| 182 | to model capture of muons at rest instead of <TT>G4MuonMinusCaptureAtRest</TT>. |
---|
| 183 | This model better reproduces the spectrum of secondaries close to the |
---|
| 184 | kinematic limit.</LI> |
---|
| 185 | <LI>The new physics list QGSP_BERT_TRV is a variant of QGSP_BERT where Bertini |
---|
| 186 | cascade model is used only up to energies of 5.4 <TT>GeV</TT> for protons, |
---|
| 187 | neutrons, pions and kaons. For comparisons QGSP_BERT uses Bertini cascade |
---|
| 188 | model up to 9.9 <TT>GeV</TT>.</LI> |
---|
| 189 | <LI>HElastic model for projectile energy above 1 <TT>GeV</TT> is used for all |
---|
| 190 | targets with <TT>Z>1</TT>.</LI> |
---|
| 191 | <LI>In all lists for electro-magnetic physics, the "skin" for |
---|
| 192 | multiple-scattering on boundaries is set to zero, meaning that no |
---|
| 193 | computation of the linear distance to the geometrical boundaries is |
---|
| 194 | made by the multiple-scattering model.</LI> |
---|
| 195 | <LI>In the QBBC physics lists, the Binary Cascade is used up to 4 <TT>GeV</TT>, |
---|
| 196 | the FTFP model between to 3.5 to 12 <TT>GeV</TT>, and QGSP above 11.5 |
---|
