    皆様、
    
    NuInt 打ち合せの最後での内部打ち合せの仕事を割り振りを確認します。
    
    Schedule 
      *) First announcement in Web -- in one week.
           Info (Outline of the program, OPC, SAC, 
           Registration form, Accomodation, Registration
           fee, Proceedings, and contribution papers) is included.
          After Local OPC decides a plan in a week, OPC will receive a
         notice and comment on it.

              Decide talks in each session in mid-August.
              Communicate via e-mails 
      *) We will see in September how many people show
        contributions to the workshop. Second bulletin may come in a 
        month. 
    
    
    1) Program の Outline
     伊藤さん:改訂版 があればよろしく。
    
         The First International Workshop on Neutrino-Nucleus Interactions
            in the few GeV region  (NuInt01)
    
                December 13-16, 2001 at KEK,
    16日はReserve なんですか。
    
          The discovery of muon-neutrino oscillations in atmospheric
      neutrinos by the Super-Kamiokande (SK) experiment has triggered
      many proposals for neutrino oscillation experiments using conventional
      low-energy neutrino beams for precise determination of the oscillation
      parameters.
    
         The accelerator-based, long-baseline neutrino oscillation
      experiment, the K2K, uses a neutrino beam with <E_nu> = 1.3
      GeV interacting with nuclei in the Super-K detector.  
       As the experiment collects more data, 
     the contribution of systematic errors may become
      more significant in the oscillation analysis. Important sources of these
      systematic errors are the uncertainty in the neutrino-nucleus cross
      sections and subsequent nuclear effects in the few GeV energy region
      such as Pauli Blocking, nucleon binding, pion absorption, nuclear
      correlations, and final-state interactions.
         Since more precise knowledge of neutrino-nucleus interactions in
      the few GeV region will also be of vital importance in the near future
      at JHF, Fermilab/MINOS and CERN/Gran Sasso, as well as future
      atmospheric neutrino experiments and next generation proton-decay
      experiments, it would be timely to organize an international
      workshop on this subject.
         The purpose of this workshop is to form and develop a strong
      community of nuclear and high-energy physicists in order to meet
      the many challenges in current neutrino physics. By examining our
      knowledge of this subject and noting where theoretical and experimental
      expertise is needed, international effort can be more efficiently applied
      to the problem.
         Note that an additional benefit of this effort may be the establishment
      of a new field of nuclear physics using neutrino beams as well as
      electron beams for precise measurements of lepton-nucleus interactions.
     
       The topics to be discussed:
          1. Neutrino-nucleus interactions, and their relation to 
             neutrino oscillations and proton decay studies
          2. Experimental review of electron-nucleus and 
             neutrino-nucleus interactions  
          3. Theoretical review of nuclear effects and calculations
          4. Comparison of neutrino event generators
          5. Where are we now - where should we direct our efforts?
          6. Future experiments for precise neutrino-nucleus interactions
     
    2)Web Update 
    
    We will set up Web page which includes a registration form,
    accomodation, registration fee, proceedings, and
    contribution papers. --- This was discussed among Japanese
    OPC after this meeting. 
    
    この Web の Contributed paper も含めたTemplate は、Topical
    Conference のものから早戸君が取ってきて、石田君に渡し
    後の体裁を作るということだったのでしょうか。
    
    加える事:
    1. Registration Fee = 100$ 
    2. Deadline of Abstract of Contributed papers --- End of September 
    3.  Urban Hotel near KEK or Hotel Okura.
     Web application is possible. They provide a transportation from Hotel to KEK.
       20 KEK dorm rooms (twins) can be reserved for young students or postdocs. 
    
    4. Poster は、まだAnnouncement には添付しないで良いと思います。
