6 Particle physics relevant requirements collected Specifically from LHC: Have starting physics list (done) Improve information flow on V&V (done, to be verified) Provide a cascade code (two focused efforts) Fix known problems in low energy models (released)
7 A complete sample requirement. Name and E Dennis Wright, SLAC Title: Pion and kaon nuclear prodution cross-sections sections Description: 1-51 GeV pions and kaons interacting inelastically.. 10% precision would be great. Rationale: Representation of how the shower develops. Supporting use-cases that require this: Trying to model hadronic interactions in the BaBar intsrumented flux return. Responsible cathegory: hadronics Fulfillment criterion: Comparison to the data from particles interacting in the beam-pipe and flux return. Relevace: : very highly relevant for BaBar,, relevant also for LHCb References: An E from Dennis pointing to the data.
8 Requirements collected titles only During the last geant4 workshop, the users workshop at SLAC, and in private mails: Ensure that the physics reference manual match the implementation, n, and the models are mentioned in the applications developers guide, Referencing papers is just fine. Memory usage for G4NDL cross-sections sections Energy and momentum conservation should be checked in regression independently by the working group for all models, and publish the t test-suite. suite. Use well known international benchmarks to validate; publish results. r More understandable hadronic physics lists Get documentation on which model is good/usefull usefull/required for which use-case
9 Requirements Cont. Provide a set of plots, and put them u; i.e. provide a place to put these plots for users. Cross-sections sections for n,p inelastic scattering below 150 MeV in CMS tracker materials at 10% level of precisions. Pion and kaon nuclear prodution cross-sections: sections: 1-51 GeV pions and kaons interacting inelastically.. 10% precision would be great % level of description for GeV 100GeV incident protons for example on Beryllium or copper. Enroll a set of users to validate on complete application; as beta testers so to say. Compare inclusive and exclusive cross-sectios sectios to data from the RAL/Durham database
10 Requirements Cont. Description on how to set cuts, and its effects Possibility to stop low energy neutral particles (like neutrons) Each model should be specified concerning its application area/use-cases Provide a list of models per use-case package List of models per use-case package Include physics list samples, once they exists, into the phsics editor Ensure tracability of data to the primary source Well defined process for updating the databases on request. Parametrizations of hadronic showers in CsI and Iron. Parametrizations of neutron background in LHC experiments Models for alpha incident inelastic reactions
11 Requirements Cont. Models for alpha incident difractive dissociation reactions Where the modelling approach allows to produce the residual, it should be provided. Neutron production by alphas at energies below 10 MeV; ; including reaction cross-sections sections at 20%precision and kinematics of neutrons and gammas produced. Include K0 oszillations Provide muon nuclear reactions Provide internal conversion Provide neutron elastic scattering, in particular recoil energy and momentum distributions for neutrons below 10MeV. Dito for n inelastic scattering off Xenon and SiO2, CaCO3, H2O
12 Requirements Cont. Dito for capture Provide gamma nuclear reactions for gamma energies of less than 100 MeV,, including cross- sections. Provide radioactive decay after transmutation. Provide k-shell k excitation in radioactive decay Activation of detector material and environment by shower particles
13 Note: Almost all of these requirements are by now fulfilled. Many were fulfilled when the issue was entered as a requirement, so only information was to be provided.the rest are to be scheduled for being addressed, according to priorities.
14 Sample plots energy deposition BTEV: All distributions are in the expected energy range
15 Active tasks 2002 Write educated guess physics lists for major use-cases Include at least one test-beam simulation into regular validation Include a complete radiation benchmark into WG level validation Improved validation suite for the cascade energy range Possibly further extension of the high energy validation suite Plan to contribute to SATIF-6 Release fully leading particle biased mars-5 5 re-write Release of cascade part of HETC re-write Improve gamma nuclear reactions in QGS model Make a validation/verification WWW page
16 Active tasks 2002, cont. Possibly first release of high energy heavy ion reactions in QGS model, with option to further extension to QMD Revision of the reaction cross-sections sections Improve the charge state treatment for recoils. Bring kinetic model to releasable state Bring inucl cascade code to releasable state Research the use of CHIPS in string fragmentation for intrinsically 3D fragmentation Provide a generic scattering term for cascade type models Alternative coherent elastic model (reggee( theory based)
17 Active tasks 2002, cont. Improve electro-nuclear cross-sections sections to take hard scattering into account. Investigate JENDL2.2, and LA150 neutron data libraries Collect (even more) requirements Release work, coordination Contribute to maintenance and user support Contribute to architecture working group Contribute to process improvement/establishment Contribute to training Publish work (11 papers in the plan )

23 The neutron_hp transport models Simulate the cross-sections sections and interactions of neutrons with kinetic energies below 20 MeV down to thermal energies. The upper limit is set only by the evaluated data libraries the code is based on. We consider elastic scattering, fission, capture and inelastic scattering as separate models Neutron_hp sampling codes for the ENDF/B-VI derived data formats are completely generic (not including (not including general R-matrix R for the time being) Note that for fission there is a quite competitive theory driven alternative model, G4ParaFissionModel.

51 GHAD Validation&Verification Our validation strategy is deployed since spring It was also submitted as paper to CHEP2001 at the time of the last review. My apologies for not having presented it last time. It was subsequently presented again in CMS and ATLAS, at the LHC-geant4 validation meeting, and the recent ACAT conference in Moscow. I would have been pleased to also present it in invited talks at the SATIF workshop, and the IDM2002 workshop, but I had to turn these down due to lack of travel-money.

86 Collaboration with 3 rd parties Some of the reasoning: Geant3 had used two strategies. There were shower packages released with geant3, and there were interfaces released with geant3; the latter were interfacing to external packages. The first was a working model, for the latter, geant3 always was claimed to be obsolete. GISMO: the no physics situation, but only interfacing to external packages. They never really got support for the use of these codes with GISMO. MCNPX: Gets it right. They encourage and help 3 rd parties to release MCNP interfaces with their 3 rd party code. It solves the support question.
87 Collaboration with 3 rd parties Basis: Basis: We provide a set of well defined, published, and highly stable interfaces that allows interested 3 rd parties to release adapters to use their code, or to use geant4 physics implementations within their infrastructure. EGS: geant4 chips code for γ-nuclear reactions also in EGS HETC: Being re-written to become natively available in G4 INUCL: Being integrated to become natively available in G4 UrQMD: In the process of being re-engineered engineered to become natively available in geant4 MCNP: Discussion on using the geant4 interfaces in MCNP FLUKA: Interfaced by air shower users for their own use. Liege Cascade code: Discussion in progress. We hope that they will release a G4 interface soon, and are of course happy to help. EGS: HETC: INUCL: UrQMD MCNP: G-FLUKA: Liege
