(Several people commented. The First International Workshop on Neutrino-Nucleus Interactions in the few GeV region (NuInt01) December 13(Thurs)-16(Sun), 2001 at KEK, 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. 5) Announcement to general participants with a registration form: (Itow/Ishida) > The registration forms will be returned and corrected by Ishida_kun > First Bulletin(Itow/Ishida) > Lists we have or we need: Neutrino98, NOON2000 participant list > Japanese Nuclear Physics Community > US COmmunity > SLAC Conf. information, Kim`s and Goodmann`s > Anouncement at APS/JPS meeting at Hawaii. 6) Accommodations (Ishida/Sakuda) 20 KEK dorm rooms can be reserved.

Several experiments, running like K2K, or under construction like MiniBOONE, MINOS, ICARUS and OPERA are designed to confirm and to elucidate the neutrino oscillations phenomenon and to provide more precise measurement of the oscillations parameters. Detailed understanding of the pattern of neutrino masses and mixing may provide a vital clue to the realm of physics beyond the standard model. Very precise experiments are necessary to study the CP violation effects in the lepton sector, to study matter effects or to measure small mixing matrix elements, like Ue3. New generations of conventional neutrino beams as well a novel approach, that of neutrino factories based on muon storage ring are necessary for these next steps in the neutrino oscillations studies. Very high statistics of the future generation of the neutrino facilities is necessary to study subtle effects. To exploit this high statistics it will be necessary to control the systematics effects at the adequate level. Many of the proposed experiments will require studies of neutrino interactions at relatively low energies, in the range of 0.5 to 10 GeV. This is the least well known regime of the neutrino physics. Neutrino cross sections, both inclusive and exclusive, are known relatively poorly. As an example, a pi-zero production by neutral currents can be a serious background for numu to nue oscillation search. Nuclear effects, like Pauli blocking, binding energy or nuclear re-scattering may lead to a systematic shift of the observed energy of the final states and cause a systematic error on the determination of the oscillation parameters. A very similar effects may become important for the next generation of the proposed nucleon decay experiments.. The aim of the workshop is to review the knowledge of neutrino interactions in a few GeV region and to identify the principal sources of possible systematic effects. The goal is to formulate a coherent program of studies, both theoretical and experimental, to improve the level of understanding. New generation of neutrino beams in conjunction with electron beam facilities, like CEBAF, offer a realistic chance for a major improvement in the experimental data. Last, but not least, it is important to point out that the studies of nuclear effects and of low energy neutrino interactions are very interesting by themselves. We hope to bring together the interested communities to establish a common study program. //
