The subsections are:
- An upgraded NuMI/Minos experiment with 3-4 times the intensity
- A neutrino oscillation experiment with a 3000 km baseline
- Lower neutrino energy (600 MeV) long baseline neutrino experiments..

- Mini-Boone type signal-region and experiments
Alberto and Larry were considering options for either 120 GeV or 16
on target. Unfortunately, 8 GeV is too low for their desired neutrino spectrum.
Steve Geer emphasized that the superbeams report
(See here for a link to the report) should be extensively recycled,
especially for the 3000 km baseline section.
2) Jorge Morfin summarized the status of the non-oscillation neutrino
He and Bonnie Fleming have assembled a group of about 5 nuclear physicists
and 5 high-energy physicists. They have sent out an invitation (link here) to the
nuclear physics community with information on the proton driver. They are
envisioning a 2nd generation short-baseline detector using the available space
near the Minos monitor chambers. They envision a cryogenic hydrogen target,
with polarization at some point. With the new proton driver, the event rate
would be 10,000 per kg-year. This, along with the ability to run with
nu and anti-nu beams would allow measurement of individual structure functions
in Q**2 bins. There are also a variety of nuclear effects to study, such as the
Hermes effect, where shadowing has been seen to depend on the nuclear
Alberto Marchionni commented that these nuclear physics measurements
be useful for understanding tau appearance signals.
3) Fritz summarized the request from the Committee
on Physics of the Universe
for input, and a draft letter. Both of these have been circulated to the e-mail list.
Revised versions will also be circulated. Send revisions to firstname.lastname@example.org and
let him know if you'd like to have your name added.
4) Jeff Nelson summarized the cost estimates in the superbeams report.
(See here for a link to the report). He, with input from Bob Bernstein and
Ray Stefanski, have made an extensive effort to compare detector costs
on an equal basis. To update the report, Jeff will try to add info on
hybrid-emulsion detectors, and the aquarich concept.
Possible R&D directions would include operating long-drift liquid
in magnetic fields, and developing new photo-detectors for water cerenkov detectors.
