Responses to IF requests Thank Laura and Carl once again for their comprehensive presenta>ons! • Four kinds of requests • – Major development requirements we will integrate into our annual work plan • Listed in our Requirements Tracking System • hRps://jira-geant4.kek.jp/secure/Dashboard.jspa – Other development / enhancement requests • Some of minor requests have been already addressed, some will come. • A few are too difficult and need to seek resources. – Support requests • Discussions have started or soon arranged. • Examples may be created for some “common” requests. – Need further communica>on / clarifica>on / diges>on • Discussions have started or soon arranged.

Both EM and hadronic showers already treated in detail as part of ongoing improvement and valida>on of models and physics lists (LHC, Calice, etc.). Further discussion in the following presenta>on. Introduction to version 10.2 and responses to the IF requests - M. Asai 9
Cosmic rays are currently reasonably well treated up to about 1 TeV using exis>ng EM and hadronic and weak models. Muon-nuclear interac>ons (and gamma-nuclear) need more data for valida>on. Also a more sophis>cated (full weak interac>on) model is required to augment the current low momentum transfer model (big job). More discussion at the following presenta>on. Introduction to version 10.2 and responses to the IF requests - M. Asai 10
Muon spin tracking process already available, and the outstanding bug was addressed with version 10.2. Patch to v10.1 underway. An>-proton produc>on handled exclusively by FTF model. Aner valida>on against G4 V 10.1 or 10.2, will see if FTF can be improved or if Ber>ni needs to be extended to handle an>-protons UR-28 Introduction to version 10.2 and responses to the IF requests - M.

Geant4 already has rudimentary capabili>es of handling these requirements. Connec>ng NEST and extending it to liquid Argon will ul>mately address them, but need resources. Pion and kaon decays already exist with sufficient detail to do par>cle ID. Was done in BaBar. Introduction to version 10.2 and responses to the IF requests - M. Asai 13

Neutron cross-sec>on is reasonably precise with Par>cle_HP (Neutron_HP). We have an op>onal model (thermal- scaRering model) to handle an atom in a molecule, though it requires dataset for each molecule. Introduction to version 10.2 and responses to the IF requests - M. Asai 29
In version 10.2 we have improved de- excita>on and radioac>ve decay modules, but there is no correla>on between more than one gammas. Further improvements are planned. UR-31 Introduction to version 10.2 and responses to the IF requests - M. Asai 30
