Geant4 9.2 - patch-04 Release Notes
|
|
-----------------------------------
|
|
|
|
16 September 2010
|
|
|
|
List of fixes included in this public patch since the public release 9.2.p03:
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ models/cascade:
|
|
o Fix for long-standing problem of energy non conservation in pion-nuclear
|
|
reaction on very light nuclei (in particular He) in G4CascadeInterface.
|
|
The workaround re-samples the interaction in the rare case when an
|
|
unphysical final state with baryon number violation is generated.
|
|
+ models/CHIPS:
|
|
o Fix in G4QEnvironment for a rare problem of anomalous event with high
|
|
pT jet observed in ATLAS, identified in a Gamma+A -> X reaction with
|
|
gamma energy of 2 GeV, for which at least one of the secondaries was
|
|
created with too much kinetic energy (up to 90 GeV).
|
|
Addresses problem report #1126 and relates only to 9.2 release series.
|
|
o Fix in G4ChiralInvariantPhaseSpace to catch previously un-handled
|
|
exceptions produced when a 'chipolino' pseudo-particle is produced by
|
|
the model and thrown by Q4QEnvironment::Fragment; handles the case in
|
|
which Q4QEnvironment returns a 90000000 fragment, and converts it to
|
|
a gamma. Addressing problem report #1138.
