Suzuki san and Sakuda san,
Following our last night's meeting, I am including below, a draft of the
letter to be sent to each of the SAC member candidates. Please
edit/correct and finalize it. (The dates of the preceding two workshops
are correct?) Thanks.
Seki
********************************
Dear Sir,
On behalf of the organizing committee of the First International
Workshop on Neutrino-Nucleus Interactions in the few GeV region
(NuInt01), I would like to invite you to participate in the Workshop
and to help us as a member of the Scientific Advisory Committee (SAC).
The workshop will be held at KEK from December 13 (Thursday) to
December 16 (Sunday) 2001, after several days following ICRR Workshop
on Neutrino Oscillations and Their Origin (NOON2001) and Low-Energy
Solar Neutrinos (Lownu2001), December 3-5 and 6-7, respectively.
The workshop is planned to be the first of a series, and the current
one will be hosted by KEK and ICRR. The short announcement below
will describe the scope and objectives of the Workshop. A web page is
being constructed.
We very much hope that you can participate and can help us as a
SAC member.
Best regards,
XXXXXXXXXXX
**************************************************************
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 the atmospheric
neutrinos in 1998 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 at relevant $ \Delta m^2$ regions.
The first long-baseline neutrino oscillation experiment, the K2K
experiment, uses a neutrino beam with <E_nu> = 1.3 GeV interacting with
the nuclei in the Super-K detector. As the experiment collect more data,
the contribution of the systematic error will become more significant
in their oscillation analysis.
One important source of systematic errors is 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.
Furthermore, in the near future, at K2K, JHF and Fermilab,
more precise knowledge of the neutrino-nucleus interactions
in the few GeV region will become of vital importance. Next generation
proton-decay experiments must take into account the background generated
by the atmospheric neutrino interactions at GeV energies. Even now,
some analyses of the atmospheric neutrinos are influenced by the
uncertainties associated with the neutrino-nucleus interactions.
Since the K2K is now observing
various neutrino-nucleus interactions with the near detectors
including charged-current neutrino interactions with the oxygens and
iron, and neutral-current interactions at the few GeV region,
it would be timely to organize the first international workshop
on this subject.
The purpose of this workshop is to form and develop a strong
community among 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.
Furthermore, the precise measurements of the neutrino-nucleus
interactions may establish a new field of nuclear physics using neutrino
beams in addition to the study of nuclear physics using electron beams.
Organizing Committee (Tentative):
D.Casper(UCI), Y.Hayato(KEK), Y.Itow (ICRR, secretary),
P.Lipari(Rome),J.Morfin (Fermi, co-chairman), K.Nakamura (KEK),
A.Para(Fermi), M.Sakuda (KEK, co-chairman), R.Seki(KEK/CSUN/Caltech),
Y.Suzuki(ICRR, co-chairman).
The topics to be discussed:
1. Neutrino-nucleus interactions, and their relation to
neutrino oscillations and proton decay studies
2. Experimental review of 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
