Conveners of each session, please discuss over the content and talks with rough time allocation, update the program and send it to OPC in a week or so. We may meet in the first week of September if it's necessary. I attach three relevant e-mails below. 1) Morfin's suggestion for time allocation. 2) Para's suggestion for Session 2 and 7. -- Agreed by Session 2 and 7 conveners. 3) Minutes from the previous meeting. Regards, Makoto Sakuda ********************************* 1) Morfin's Proposal: Day 1 1) Welcome 2) Objectives and Motivations (Sakuda*,Suzuki, Lipari) 3) Review of e-Nucleus (Morfin*, Seki, Lipari, Para) Day 2 3) Neutrino Nucleus Theory (Morfin*, Seki, Lipari, Para) 4) Overview of existing/new Neutrino-Nucleus (Itow*/Suzuki/Sakuda) Day 3 5) Comparison of Monte Carlos 6) Panel Discussion (Seki*/Hayato/Casper/H.R.Gallagher Day 4 7) Future Experiments and Facilities (Para*,Itow,Walter) 8) Closing Remarks **************************** 2) Para's suggestion on Session 2 and 7 Date: Sat, 25 Aug 2001 17:40:49 -0500 From: Jorge_G_Morfin <morfin@fnal.gov> To: Makoto Sakuda <sakuda@neutrino.kek.jp>, Adam Para <para@fsgi03.fnal.gov> cc: <suzuki@suketto.icrr.u-tokyo.ac.jp>, <itow@neutrino.kek.jp>, <walter@neutrino.kek.jp>, <lipari@rccn01.icrr.u-tokyo.ac.jp> Subject: Re: Session 2 and 7 In-Reply-To: <200108252131.f7PLV3p4613394@fsgi03.fnal.gov> Message-ID: <Pine.SGI.4.31.0108251725180.5955424-100000@fsgi01.fnal.gov> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Dear Makoto and Adam, I agree with Adam that session 2 and 7 ssem to be covering different material. In particular I had interpreted session 7 as an appropriate way to end the workshop with a "look to the future" theme. The session would cover, in my interpretation, possible future low-energy neutrino-nucleus experiments and other FUTURE electro-production nuclear effects type experiments. I emphasize FUTURE here since in Adam's current vision of session 7 he has included a "review of CEBAF electron-nucleus scatering experiments". Obviously Adam and I, with offices a few meters apart, need to talk about this since I have been lining up names of speakers to review Jlab and HERMES results as part of session 3! I was planning to send out the list to my co-conveners tomorrow (I've been waiting for input from Argonne colleagues who have just returned from vacation). Adam and I will combine names and propose which session should contain the electro-production review.

Welcome address by S.Yamada (KEK) 2. session "Objectives and Motivations" (Sakuda*,Suzuki, Lipari) (a) Precise Measurements of neutrino oscillation parameters with Long-Baseline accelerator beams - 1st generation: K2K, Minos, Opera - Next generation(s): Superbeams, nu-factories (b) Determination of neutrino oscillation parameters with atmospheric neutrinos. *)How much is each neutrino oscillation experiment affected by the systematic errors due to cross sections and nuclear effects? *)Prospects of the current and near future experments on neutrino cross section measurements and nuclear effects. (c) Background studies for proton decay (d) Astrophysics (?) (SN seems to be the most interesting subject) (e) Particle physics (?) [axial form factors, from hard to soft in QCD, ...] We must find a speaker for d). --> Toki (app. to SN simulation?, axial vector…?) --> Haxton 3. Theoretical issues in the neutrino interaction and nuclear effects (Conveners: Morfin*, Seki, Lipari, Para) 1) What is known in electron-nucleus interactions (e,e') and (e,e'p) about nuclear effects in relation to the corresponding neutrino-nucleus interactions at 0.5 to 10 GeV resgion. *) V.R. Pandharipande -- Theoretical Review *) Philipone (he has been in CEBAF PAC committee) or his recommended speaker -- Experimental Review a) Fermi gas model b) Nuclear correlations c) Final-state interactions such as nucleon rescattering d) Exchange current effects e) pi,K,Lambda absorption in nucleus 2) Phenomenological review in relation to neutrino-nucleus interactions 4. Overview of the existing and new data on neutrino-nucleus interactions and their uncertainties (Conveners: Itow*/Suzuki/Sakuda) a) Nu-nucleon and -deuteron Data and their systematic uncertainty /Theoretical comments b) Nu-nuclei Data and their systematic errors d) Atomospheric data e) Continuation from/to the DIS and resonance regions -- Morfin will ask C.Keppel (Jefferson Lab) to give a talk. f) K2K data i) CC 1kton (Water) MRD (Fe) SciFi (Water) ii) NC (pi0) CC (mu-pi0) g) Proton decay data Study of the proton decay backgrounds by the measruements / Mu-pi0 study really estimates e-pi0 backgrounds? / Kaon production by neutrino interactions (BEBC?/K2K) *) Specify the accuracy of the cross section measurements and of verifying nuclear effects, even if the measurement is direct or indirect. 5. Comparison of the benchmark MC and theoretical calculations Conveners: Seki*/Hayato/Casper/H.R.Gallagher Generators: a) NEUT (Hayato) b) NUANCE (Casper) c) MINOS/Soudan II (Gallagher) d) OPERA/NOMAD/DONUT Comparison: a) Quasi-elastic b) Charged pion production c) Coherent pi0 production *) It is important that all groups use the same parameters for the neutrino-nucleon cross sections, for example, vector and axial form factors. Then, specify which models or papers they use for nuclear effects (Fermi-gas model etc). We compare the basic distributions for leptons, protons or their correlations. Note: Seki will organize this comparison session. 6. Panel Discussion with nuclear physicists Summary and Future Direction may be discussed. 7. Future experiments and facilities (Conveners: Para*,Itow,Walter) a) K2K/JHF b) Near detectors; NUMI c) Cross section measurements at CERN AD, Fermilab Debuncher d) Nu-factory 8. Closing remarks and announcement of the next workshop (Convener: Suzuki*) - -------------------
