Geant4 11.0 - patch-03 Release Notes ------------------------------------ 16 September 2022 List of fixes included in this public patch since the public release 11.0.2: o Configuration ------------- + CMake: o Update extraction of include paths from VecGeom to use imported target property. Addressing problem report #2485. o Geometry: -------- + management: o Added protection in G4GeometryManager for Open/CloseGeometry() to be executed only by master thread. Addressing problem report #2502. o Global: ------ + Commented out debug printout in G4ThreadLocalSingleton method. + Updated date and version for 11.0.3. o Parameterisations: ----------------- + gflash: o GFlashHitMaker: fix to make it compatible with command-based scorer. o Particles: --------- + Fixes for transportation of hypernuclei and anti-hypernuclei: in G4Ion, set (forgotten) 'isGeneralIon' to false for hypernuclei and anti-hypernuclei, to avoid they get assigned same processes as 'GenericIon'. In G4DoubleHyperDoubleNeutron and G4AntiDoubleHyperDoubleNeutron, added (forgotten) call to SetDecayTable(), to have the decay table defined for these particles. In G4ParticleDefinition, protect methods GetNumberOfLambdasInHypernucleus() and GetNumberOfAntiLambdasInAntiHypernucleus() against baryonic resonances with high spins (such as N(2220), N(2250) and their anti-particles) which have 8-digits PDG codes, but which are not hypernuclei or anti-hypernuclei. o Physics Lists: ------------- + constructors/electromagnetic o G4GammaGeneralProcess: fixed problem of Compton scattering selection in the low energy interval < 150 keV. o Processes - Electromagnetic: --------------------------- + utils o G4EmExtraParametersMessenger: fixed typo. Addressing problem report #2492. o Processes - Generic: ------------------- + cuts o G4VRangeToEnergyConverter: fixed static methods to provide correct initialisation of energy limits. o Processes - Hadronic: -------------------- + models/particle_hp o G4ParticleHPInelastic, G4ParticleHPCapture, G4ParticleHPFission, G4ParticleHPElastic, G4ParticleHPThermalScattering: replaced the threshold used for checking the absolute energy non-conservation from DLB_MAX (implying no checking at all) to 350 GeV (this value allows for cases where the residual nucleus is not produced, even when super-heavy nuclides are involved). o G4ParticleHPContAngularPar: added protections against evaluations of arrays at negative index (-1), fixing rare reproducibility problems. + models/parton_string o Fixes to get isotropic distributions in annihilations at rest: in G4DiffractiveSplitableHadron, set proper parton index. In G4DiffractiveExcitation, in the CreateStrings() method, take into account that strings are created in G4FTFAnnihilation; by default, the method CreateStrings() creates a string from a wounded nucleon/hadron, but this is not needed in the case of annihilation. In G4FTFAnnihilation, removed splitting of hadron; fixed bugs in the calculations of kinematical properties; set quark momenta at string ends, to properly account for string order on rapidity. o G4VSplitableHadron: changed the method Splitting() from "protected" to "public" (needed to change the status of SplitableHadron in G4FTFAnnihilation, to get isotropic distributions in annihilations at rest). o Track: ----- + G4Step: added ResetPre/PostStepPoint() methods to replace a StepPoint without deleting the previous object. ---------------------------------------------------------------------------- Technical Notes --------------- o This patch should be applied on top of release 11.0 series. o Technical notes distributed for release 11.0 are also applicable and valid for this patch. The code and rebuilt binary libraries for release 11.0.3 are available through the Geant4 "Download" Web page. Please refer to the Geant4 User Documentation for further information about using Geant4.
