PS: Dave sent me a message saying that his building was
blown up by a chemistry student and set on fire last
Monday. Although his wing did not burn,
no one is allowed to enter it this week.
He was not able to attend, even come close to, the meeting.

4) Preface
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:
We (Local OPC) will fix the first bulletin within a week.
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.
> Lists we have or we need: Neutrino98, NOON2000 participant list
Seki --- Japanese Nuclear Physics Community
Walter --- DPF bulletin
SLAC Conf. information, Kim`s and Goodmann`s
Suzuki --Announcement at APS/JPS meeting at Hawaii.
Lipari -- Announcement at Lepton Photon Conference
6) Accommodations (Ishida/Sakuda)
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. Need final agreement
from KEK Division Heads. We recommend KEK dorms for young
students or postdocs.
7) VISA?
8) Home page (Hayato+Ishida)
9) Poster
Anyone can propose a good poster.
========================================================================
10) Tentative Program:
Names in () are the conveners, who are responsible for
organizing the talks and speakers in the session.
The one with *) in () is in charge of the session.
1. Welcome address by S.Yamada (KEK)
2. Objective and motivation of the workshop
(Conveners: Sakuda,Suzuki,Lipari)
a) We need overview:
*)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.
b) Effect of neutrino interactions to atm-neutrino analysis
--> Lipari, Kaneyuki
c) Contributions to the proton decay search
d) Astrophysics and new Physics
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
-- P.Vogel ?
*)Seki will send the info (Pandharipande et al) to Morfin.
4. Overview of the existing and new data on
neutrino-nucleus interactions and their uncertainties
(Conveners: Sakuda/Itow/Suzuki)
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
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
*) Lipari will tell us the name for OPERA/ICARUS MC.
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.
*) Morfin will contact E.A.Paschos (Dortmund).
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*)
> =====================================================================
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.
*) Beginning of September --- OPC meeting
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
