Notes
1. Introduction
YN thanked LR for his
efforts in organising the successful Boston Workshop.
2. Summary
of Boston
YN, OY, and KL each had
attended the
OY reported that two
phenomenological talks were presented (Friedland, Marfatia – see w/s page). A contribution on the Braidwood
reactor experiment (Fisher) summarised the status of preparations and the
sensitivity to θ13. Several theory talks (Langacker,
Everett, Murayama, Tegmark,
Glashow) reviewed
theoretical framework. Marciano reported on the
possible muon physics using the muons from a Neutrino Factory. The experimental
subgroup contributions had been confined to a contribution from P.Huber because others making contributions were unable to
attend. P.Huber had made significant progress in
determining desirable parameters for the Neutrino Factory detector. In
addition, it was shown that if θ13 is large, a NF with a muon
energy of 20 GeV and a baseline of 1000 km was a good option. A phone
call was organised with A.Bross and M.Ellis at FNAL to exchange information on the detector
performance desired and that which the magnetised-sampling-calorimeter might
provide.
3. Program
of the RAL meeting.
The talks OY is inviting
for the phenomenology session at the RAL meeting are:.
● S.Geer: Neutral
currents and tests of three-neutrino unitarity in
long-baseline experiments
● C.Volpe: Double beta
decays and nu-nucleus interactions
● C. Penya-Garay: Unitarity of the
lepton sector
● O.Yasuda: Model independent analysis of new physics
interactions and implications for long baseline experiments
YN commented that C.Albright and P.Harrison had
volunteered talks and should be invited. OY agreed to contact SK to see if
these contributions could be solicited.
KL had invited W.Winter to present the work of the Lindner,Huber,Winter team on NF optimisation. E.Couce had agreed to present a comparison of super-beam
and beta-beam sensitivities. In addition, KL argued that a joint session with
the detector group should be organised in which the programmes needed to reduce
the systematic errors to the required values would be discussed. KL had already
organised a talk from a geologist to address the matter density uncertainty.
MM reported that he and A.Donini had just started to consider speakers from the
BENE physics group. It was likely that there would be a contribution on SUSY,
other contributions were being solicited.
YN suggested that a
Physics Working Group discussion be organised on the afternoon of Monday
24Apr06. KL agreed to organise a room and to contact the group to advertise the
meeting.
Action 3.1: KL: Book room and
advertise Physics Group discussion on Monday 24Apr06
4. A possible workshop after RAL meeting
KL reported that he had
been in email discussion with PH in the hope of holding the third w/s in
Action 4.1: KL: Discuss with PH
third w/s in
5. More details of the final report
contents
SK had prepared a
contribution. OY was planning a contribution on non-standard interactions and testing
the unitarity of the MNS matrix. YN emphasised the
importance of a skeleton document. KL agreed to get a skeleton including the
contributions to date produced as soon as possible.
Action 5.1: KL: Produce skeleton
report document asap!
6. Any other items
All to prepare agenda for RAL meeting – deadline 31Mar06.
Action 6.1: All: Prepare agenda for RAL meeting by 31Mar06.
KL to organise next Council call in two weeks time.
Action 6.2: KL: Organise next Council phone call in two weeks.
