Thanks for the bug report. There were problems in kinematics of sampling. The fix will be available in the next patch to 10.1. VI |
eeToHadrons energies of secondaries much higher than primary Observed in extended/electromagnetic/TestEm6 in geant4-10-01 without any change in code, with the following input /tracking/verbose 2 /run/initialize /testem/phys/SetAnnihiToHadronFac 10000 /gun/particle e+ /gun/energy 1.5 TeV /run/beamOn 10 The output shows secondaries with energies like :----- List of secondaries ---------------- pi+: energy = 3.327 PeV time = 127.6 ps pi-: energy = 309.7 TeV time = 127.6 ps gamma: energy = 6.774 GeV time = 127.6 ps :------------------------------------------ or much higher than the gun particle. We suspect incorrect use of Lorentz boost in G4eeToHadronsModel::SampleSecondaries. Cheers, Belgin and Helmut fatma.belgin.pilicer@cern.ch Helmut.Burkhardt@cern.ch
