Note: most of the considered light anti-hypernuclei projectiles have baryon number equal to -4 : it is assumed that their properties are similar to anti-He4, therefore their elastic scattering is set-up as for anti-He4 elastic nuclear scattering. These properties can be improved in the future if theoretical estimations will be available. ## 2022-09-05 Ben Morgan (hadr-cohe-V11-00-03) - Update dependencies to address warnings from consistency check ## 2022-02-04 Vladimir Ivanchenko (hadr-cohe-V11-00-02) - G4ElasticHadrNucleusHE, G4NeutronElectronElModel, G4NeutrinoElectronNcModel fixed compilation warnings on unused variables; removed commented lines; use Energy(..) method of G4PhysicsVector instead of obsolete GetLowEdgeEnergy(...) ## 2022-01-03 Alberto Ribon (hadr-cohe-V11-00-01) - G4AntiNuclElastic : Vladimir Uzhinsky's correction in the SampleInvariantT method of the highest momentum transfer (which was causing the cosine of the polar angle in the center-of-mass system to be larger than 1 in some cases). This should be fixed bug #2204. ## 2021-12-10 Ben Morgan (hadr-cohe-V11-00-00) - Change to new Markdown History format --- # History entries prior to 11.0 04 August 2021 - A.Ribon (hadr-cohe-V10-07-04) -------------------------------------------------- - G4HadronElastic, G4LEnp, G4LEpp, G4LEHadronProtonElastic, G4NeutronElectronElModel, G4NeutrinoElectronNcModel, G4ChargeExchange, G4LMsdGenerator : set the creator model ID for the secondaries created, using the new version of G4PhysicsModelCatalog 16 April 2021 - Ben Morgan (hadr-cohe-V10-07-03) -------------------------------------------------- - Migrate build to modular CMake API 05 May 2021 - V.Ivanchenko (hadr-cohe-V10-07-02) --------------------------------------------------------------- - G4LEHadronProtonElastic, G4ChargeExchangeProcess - removed unused headers 13 April 2021 - A.Ribon (hadr-cohe-V10-07-01) --------------------------------------------------------------- - GNUmakefile, sources.cmake : removed the subdirectories hadronic/models/management and hadronic/models/util (that have been now deleted, with their classes moved to hadronic/util and hadronic/management). 08 March 2021 - A.Ribon (hadr-cohe-V10-07-00) --------------------------------------------------------------- - G4ChargeExchangeProcess : replaced Gheisha elastic cross section (that has been deleted) with G4ComponentGGHadronNucleusXsc. 22 July 2020 - V.Ivanchenko (hadr-cohe-V10-06-03) --------------------------------------------------------------- - G4HadronElastic - added numerical protection against precision lost addressing problem #2253 30 April 2020 - B.

Folger (hadr-cohe-V10-05-09) --------------------------------------------------------------- - remove using namespace std and using namespace CLHEP from header file G4NeutronElectronElModel.hh 15 November 2019 - V.Ivanchenko (hadr-cohe-V10-05-08) --------------------------------------------------------------- - G4HadronElastic : Change warning printout, in the case if sampled t>tmax resample using simple algorithm, protect this warning by G4VERBOSE, this is a partial fix of #2204 06 November 2019 - A.Ribon (hadr-cohe-V10-05-07) --------------------------------------------------------------- - G4HadronElastic : Coverity fix in the unused method GetSlopeCof. 31 October 2019 - V.Ivanchenko (hadr-cohe-V10-05-06) -------------------------------------------------------- - G4ElasticHadrNucleusHE - reduction of size of data structure and time for initialisation ~2 times; general code clean-up; addition of protections 07 October 2019 - V.Grichine (hadr-cohe-V10-05-05) --------------------------------------------------------------- - G4hadronElstic - new method for s-,c-,b-particle - ds/dt slope modifications in preparation 03 July 2019 - V.Ivanchenko (hadr-cohe-V10-05-04) -------------------------------------------------------- - G4ElasticHadrNucleusHE - general clean-up of the code - G4HadronElastic - added new parameterisation of A.Yeltokov 14 May 2019 - A.Ribon (hadr-cohe-V10-05-03) -------------------------------------------------------- - G4HadronElastic : numerically safer treatment of the very rare cases in which cos(theta) is either greater than 1.0 or smaller than -1.0 (in the first case, we assume no interaction and the projectile keeps going unchanged; in the second case, we assume that the projectile stops and its kinetic energy is deposited locally, neglecting the recoil of the target nucleus). 10 May 2019 - V.Ivanchenko (hadr-cohe-V10-05-02) -------------------------------------------------------- - G4ElasticHadrNucleusHE, G4LEpp, G4LEnp - clean-up - G4LowEHadronElastic - new model class 29 April 2019 - V.Ivanchenko (hadr-cohe-V10-05-01) -------------------------------------------------------- - G4HadronElastic - added protected variable pLocalTmax, added protection for zero energy primary; G4ChargeExchange - updated interfaces, added protection for zero energy primary G4ElasticHadrNucleusHE - make all data shared between threads G4AntiNuclElastic - do not compute trigonametric functions, which are not used 19 April 2019 - V.Ivanchenko (hadr-cohe-V10-05-00) -------------------------------------------------------- - G4HadronElastic - improved description and comments; added C++11 keywords 05 November 2018 - V.Ivanchenko (hadr-cohe-V10-04-08) -------------------------------------------------------- - G4HadronElastic - fixed numberical instability when final kinetic energy of projectile is nearly zero 17 August 2018 - A.Ribon (hadr-cohe-V10-04-07) -------------------------------------------------------- - G4DiffuseElastic, G4DiffuseElasticV2, G4NuclNuclDiffuseElastic : increased the number of equal-sized logarithmic-energy bins (from 200 to 300) in order to have no larger bins up to 10 PeV. - G4NuclNuclDiffuseElastic : replaced the high-energy limit of applicability of the model from 1 TeV to the value specified in G4HadronicParameters. 16 August 2018 - V.Ivanchenko (hadr-cohe-V10-04-06) 15 August 2018 - V.Ivanchenko (hadr-cohe-V10-04-05) -------------------------------------------------------- - G4AntiNuclElastic - do not delete component end of run 06 August 2018 - A.Ribon (hadr-cohe-V10-04-04) -------------------------------------------------------- - G4HadronElastic, G4DiffuseElastic, G4DiffuseElasticV2, G4hhElastic, G4ChargeExchange, G4NeutrinoElectronNcModel : replaced the explicit high-energy limit of hadronic physics with the one from G4HadronicParameters . 01 August 2018 - V.Ivanchenko (hadr-cohe-V10-04-03) -------------------------------------------------------- - G4AntiNuclElastic - proper deletion of component end of run 18 July 2018 - V.Ivanchenko (hadr-cohe-V10-04-02) -------------------------------------------------------- - G4AntiNuclElastic - use cross section component from G4CrossSectionDataSetRegistry and do not delete it end of run 20 Mar 2018 - A.Ribon (hadr-cohe-V10-04-01) -------------------------------------------------------- - Set to 100.0 TeV (instead of 1 TeV) the upper limit of applicability for the model G4DiffuseElastic and G4DiffuseElasticV2 (the number of equally-sized logarithmic energy bins has been increased from 200 to 250 to keep the same bin size (0.04) ). The model has been validated with experimental data up to 300 GeV, but it should not give meaningless results well above this energy. 14 Dec 2017 - A.Ribon (hadr-cohe-V10-04-00) -------------------------------------------------------- - Re-tag of the previous tag (incorrectly named). - Grichine's update of G4hhElastic to take into account the recent TOTEM data for proton-proton at 13 TeV. 24 November 2017 - W. Pokorski (hadr-cohe-V10-03-07) -------------------------------------------------------- - Added new class G4DiffuseElasticV2. The underlying physics model is the same as in G4DiffuseElastic by V.Grichine, however, the code has been revised, cleanup and significantly improved in a number of places. The performance has been improved by the factor of ~2 with respect to the original implementation. The approximation of small angles has been droped (replaced by exact calculation) as it was not bringing any visible benefits. 19 Oct 2017 - A.Ribon (hadr-cohe-V10-03-06) -------------------------------------------------------- - G4NuclNuclDiffuseElastic : Grichine's simplification of this class to avoid reproducibility violations in ion-ion elastic scattering. On-the-fly sampling of the nucleus-nucleus elastic scattering is done according to the Coulomb law in the limits 0 < theta < thetaC, where thetaC is the Coulomb grazing angle: this means that hadron elastic works like Coulomb in the limits. 23 Jun 2017 - Dennis Wright (hadr-cohe-V10-03-05) -------------------------------------------------------- - G4NuclNuclDiffuseElastic ctor: variables fCofAlphaMax and fCofAlphaCoulomb were first set to non-zero values (1.5 and 0.5, respectively), then zeroed a few lines later. This caused a zero scattering angle and no elastically scattered target particle. Fixed in response to bug report #1979. 13 Jun 2017 - A.Ribon (hadr-cohe-V10-03-04) ----------------------------------------------------------------- - G4NeutronElectronElModel : Coverity fix. 29 May 2017 - A.Ribon (hadr-cohe-V10-03-03) ----------------------------------------------------------------- - G4NeutronElectronElModel : added (by Grichine) model for neutron-electron elastic scattering. It produces recoil electrons resulting in visible energy deposition. The model is based on ultra-relativistic approximation of the Rosenbluth formula, since recoil electrons will have enough energy to be detected in the case of high energy neutrons, roughly > 1 GeV. 23 May 2017 - A.Ribon (hadr-cohe-V10-03-02) ----------------------------------------------------------------- - G4NeutrinoElectronNcModel : fixed (by Grichine) bug on the Plab calculation in the G4NeutrinoElectronNcModel::ApplyYourself method. 11 April 2017 - A.Ribon (hadr-cohe-V10-03-01) ----------------------------------------------------------------- - Forgot to add the (new) class G4NeutrinoElectronNcModel in the sources.cmake. 11 April 2017 - A.Ribon (hadr-cohe-V10-03-00) ----------------------------------------------------------------- - G4NeutrinoElectronNcModel : added new class by Vladimir Grichine for the final-state model of elastic neutrino-electron scattering. This class is useful for dark matter and neutrino experiments. 12 August 2016 - A.Ribon (hadr-cohe-V10-02-01) ----------------------------------------------------------------- - G4hhElastic : fixed wrong pointer initialization; - G4NuclNuclDiffuseElastic : comment out redundant if-statement. (fixes suggested by the PVS-Studio static code analyzer) 14 January 2016 - A.Ribon (hadr-cohe-V10-02-00) ----------------------------------------------------------------- - G4LMsdGenerator : hadronic internal decay scheme was restored allowing stable decay of the Roper resonances 13 November 2015 Gunter Folger (hadr-cohe-V10-01-19) -------------------------------------------------------- - Revert back to G4float, add "f" for initialisation. 13 November 2015 Gunter Folger (hadr-cohe-V10-01-18) -------------------------------------------------------- - Replace G4float by G4double 09 November 2015 - V.Ivanchenko (hadr-cohe-V10-01-17) ----------------------------------------------------------------- - G4ElasticHadrNucleusHE - fixed long standing Coverity report 05 November 2015 - A.Ribon (hadr-cohe-V10-01-16) ----------------------------------------------------------------- - Removed not needed dependency on neutron_hp/ . 22 October 2015 - A.Ribon (hadr-cohe-V10-01-15) ----------------------------------------------------------------- - G4DiffuseElastic : bug-fix made by V.Grichine in BuildAngleTable to improve the angle bin accuracy at high energies. 08 September 2015 - A.Ribon (hadr-cohe-V10-01-14) ----------------------------------------------------------------- - G4LMsdGenerator : fixed uninitialized variable which caused non-reproducibility. 13 August 2015 - A.Ribon (hadr-cohe-V10-01-13) ----------------------------------------------------------------- - G4LMsdGenerator : Grichine included in diffraction dissociation the resonances recommended by the COMPASS experiment. 10 August 2015 - A.Ribon (hadr-cohe-V10-01-12) ----------------------------------------------------------------- - G4ElasticHadrNucleusHE, G4AntiNuclElastic, G4ChargeExchange, G4LEnp and G4LEpp : checking of 'while' loops. 06 August 2015 - A.Ribon (hadr-cohe-V10-01-11) ----------------------------------------------------------------- - G4HadronElastic, G4AntiNuclElastic, G4hhElastic, G4LEHadronProtonElastic, G4DiffuseElastic, G4NuclNuclDiffuseElastic, G4LMsdGenerator, G4ChargeExchangeProcess and G4ChargeExchange : replaced std::exp, std::log and std::pow with the faster G4Exp, G4Log and G4Pow. This changes the random number sequence. 13 July 2015 - A.Ribon (hadr-cohe-V10-01-10) ----------------------------------------------------------------- - G4LMsdGenerator : Grichine has improved the resonance masses, taking them from G4ParticleTable. 17 June 2015 - A.Ribon (hadr-cohe-V10-01-09) ----------------------------------------------------------------- - G4LMsdGenerator : Grichine has disactivated the internal elastic scattering of dissociated hadron. 08 June 2015 - V.Ivanchenko (hadr-cohe-V10-01-08) ----------------------------------------------------------------- - G4ElasticHadrNucleusHE - fixed Coverity defect; substitute std log, exp, pow by G4Exp and G4Log; added check on max Z - G4NuclNuclDiffuseElastic - fixed trivial Coverity reports 26 May 2015 - R.Hatcher (hadr-cohe-V10-01-07) ----------------------------------------------------------------- - Remove unnecessary "using namespace std" from various headers that causes problems w/ G4AnyMethod & G4GenericPhysicsList when using clang and/or vc12 20 May 2015 - V.Grichine ----------------------------------------------------------------- - G4LMsdGenerator : the final state for pi+- DD was changed according to recent COMPASS data. 19 May 2015 - G.Folger (hadr-cohe-V10-01-06) ----------------------------------------------------------------- - Migrate Description() to ModelDescription(std::ostream&) for G4ChipsElasticModel, G4ElasticHadrNucleusHE, and G4HadronElastic 21 April 2015 - A.Ribon (hadr-cohe-V10-01-05) ----------------------------------------------------------------- - G4LMsdGenerator : V.
