Message-Id: <200109061007.TAA05424@neutrino.kek.jp> To: opc.nuint01 Subject: NuInt01 OPC meeting on Sep.8, 8:00am (JST) Date: Thu, 06 Sep 2001 19:07:06 +0900 From: Makoto Sakuda <sakuda@neutrino.kek.jp> Dear NuInt01 OPC members, I have merged the lists of topics and speakers which Session Convener sent us. There will be some minor changes before the meeting. At the meeting, Session Convener will explain the current proposed topics and speakers of each session. Adam (Session7 convener) will be absent from the meeting. Regarding Dave's question to Session 4: >Second, add to Item #4 (Neutrino-Nucleus Review) an explicit mention of >the goal of collecting first a comprehensive list of references to all >existing neutrino data, and for the longer term, putting as much data as >possible into some kind of computer-accessible database. 1)A comprehensive list of references to all existing neutrino data -- This is almost done now (except high energy CCFR/CDHS data). 2) Regarding the computer-accesible data base, some of the data are available in WWW server (PDG database), but selecting only interesting neutrino data is not easy. Making database from the papers may be easier.

Welcome address by S.Yamada (KEK) 2. Objectives and Motivations (Conveners: Sakuda*,Suzuki,Lipari) > - session 2 is to identify the characteristics of neutrino interactions > and nuclear effects which are relevant to various oscillation measurements. > I would try very much to avoid doing it per specific experiment (like K2K, > MINOS, etc..) to avoid yet another PR session. I would rather try to > appoint people to think about > - delta m measurement > - nue appearance > - nu tau appearance > - mixing angle measurements > - CP violation > > and identify what are the uncertainties, once we want to achieve high > precision. Presumably they will be pretty much in common in all experiments. > Some uncertainities may be bigger or smaller, depending on the type of the > detector (like pi-zero background to nue appearance in water Cerenkovs and > in ICARUS) but this van be discussed in a very generic way. Precise Measurements of neutrino oscillation parameters with Long-Baseline accelerator beams *)How much is each neutrino oscillation experiment affected by the systematic errors due to cross sections and nuclear effects? 1) nu-mu->nu-mu and nu-mu->nue at K2K and JHF ---- Y.Itow 2) nu-mu->nu-mu and nu-mu->nue at MINOS/CNGS ---- (MINOS) 3) nu-mu->nu-tau appearance experiment --- Komatsu* (Nagoya) 4) neutrino-factory --- S2-4 (Please recommend) 5) Determination of neutrino oscillation parameters with atmospheric neutrinos. -- E.Kearns or Kajita/Kaneyuki 6) Prospect of the proton decay experiment and background for proton decay -- Shiozawa (ICRR) or (UNO) 7) Supernova -- K.Langanke* 8) Particle Physics --- Mangano * Confirmed I think that the above 1) and 2) meet the request that people want to know the difference between water detector and calorimeter detector. The above 1) and 2) are simpler for a speaker than those like 1) nu-mu disappeance experiment explain K2K,MINOS,JHF , water and iron 2) nu-mu->nue appearance experiment explain K2K,MINOS,JHF , water and iron This is really hard for a speaker. I ask your comments. 3. Theoretical Issues of Neutrino-Nucleus Interactions and Nuclear Effects (Conveners: Morfin*, Seki, Lipari, Para) *) 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. 1) NUCLEAR EFFECTS IN ELECTRON-NUCLEUS INTERACTIONS THEORY: V. Pandharipande* - multi-body theory of e-Nucleus interactions T. Thomas (Backup; M. Strikman) - nonP/PQCD look at e-Nucleus int. W. Melnitchouk - Resonance region to DIS, q-hadron duality 2)EXPERIMENT: I. Sick (Backup; R. Milner) - low energy nuclear effects C. Keppel/JLAB (Backup: G. Garvey) - elastic to resonance to DIS nucleon & nucleus 3) PION-ABSORPTION STUDIES R. Redwine - LADS pi absorption experiment results 4) NEUTRINO-NUCLEUS INTERACTIONS INCLUDING NUCLEAR EFFECTS E. Paschos* - Neutrino nucleus interactions and Leptognesis O. Benhar - Final State Interactions in Neutrino Nucleus Scattering J. Marteau - although in MC benchmark session, talk to give the details of physics going into MC (Backup; P. Bernardini - nuclear re-interactions, P. Vogel for sub-GeV presentations) 4. Overview of the existing and new data on neutrino-nucleus interactions and their uncertainties (Conveners: Itow*/Suzuki/Sakuda) *) Specify the accuracy of the cross section measurements and of verifying nuclear effects, even if the measurement is direct or indirect.

Comparison of the benchmark MC and theoretical calculations Conveners: Seki*/Hayato/Casper/H.R.Gallagher Chair: R.Seki, Associate Chair: Y.Hayato Benchmark calculations are presented for: a) Quasi-elastic *) (nu_mu,mu) inclusive *) (nu_mu,mu p) semi-inclusive 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.

Casper Panel discussions are carried out by: V. R. Pandharipande, Y.Hayato, K. Kaneyuki, P. Vogel, K. Kubodera, K. Langanke, Resonance/DIS The following six issues are discussed. An leader is assigned for each issue, who is responsible to come up with consensus among the panelers and the audiance on the current status of the issue in 30 minutes. For each topic, the leaders are first to describe his view of the issue briefly (say, 5-10 minutes), and discussions are to follow it. The leaders will be responsible to write a summary for the proceedings. Tentative leaders are listed in parentheses. In MC environment for (nu,l) and (nu,l p), separately: 1) How should Fermi gas model be applied and made realistic? (Vogel) 2) How important nuclear correlations are and how should be incorporated, and how the final-state interactions are best treated? (Pandharipande) 3) How should the pion production be treated? (Hayato/Kaneyuki) As an item which is uncertain but likely to have practical consequences: 4) How vector current is made to be conserved in nuclei, off-shell effects should be treated, and how the axial currents and form factors are modified in nuclei? (Kubodera) 5) Resonances/DIS (what and who?) 6) DIS (what and who?) General discussion: 7) The universal neutrino-nucleus MC code. (Casper) The questions are to be addressed: Whether and how such a code be constructed? What is its scope (reaction processes and energies etc. to be covered)? What ingredients (physics) should such code(s) includes? Who would actually do the work? 8) Compilation of neutrino-nucleus interactions (Casper) Summary of this session will be given in Session 8. 7.
