International scoping study of a future
Neutrino Factory and super-beam facility

Physics working group

Council meeting 2:

Phone meeting: 14Sep05, 22h00 GMT

Present: K. Long, Y. Nagashima, L. Roberts, O. Yasuda

Apologies: D. Harris, P. Hernandez, M. Lindner, H. Murayama

Notes

1. Introduction Y. Nagashima

HM resigned from role of theoretical subgroup convener due to pressure of work, however, he will continue to serve on the Council. YN has contacted S.Geer asking for a suggestion of a replacement.S.Geer will nominate soon.

Good progress on the plenary meeting agenda. J.Ellis is not yet confirmed. KL to try to contact him by phone this week. If no luck by Friday LR will make the presentation. The unitarity speaker is not yet decided. KL to contact Valle by email and phone.

Action 1.1: KL: Contact Ellis and Valle.

YN proposed a half hour Council session on Thursday morning (09h30) to discuss plans. All agreed that this was a good idea.

2. Notes from previous meeting and review of actions

3. Discussion of ISS meeting #1:

Notes above.

3.1 Introduction to sub-groups:

Theoretical sub-group introduction

To be defined when theoretical subgroup convener is defined.

Phenomenological subgroup introduction O. Yasuda

Introduction to standard phenomenology, three flavour mixing, degeneracy and correlations. Will comment on unitarity issues. Need to develop list of possible models for unitarity violation and then see how to distinguish.

Plan to comment that previous analyses did not take into account uncertainty of matter effect in limits.

Experimental subgroup introduction K. Long

Goal would be to try and define the type of results that the study should seek to generate and indicate the assumptions that need to be made (machine and detector performance). Would need to address the performance of each facility independently as well as in combination.

Muon flavour violation

YN suggests that organisation on lepton-flavour violation in muons could be strengthened either by creating a subgroup on muon physics or by co-opting a muon theorist to the Council.

Action 3.1: LR: Consider how best to strength muon representation in physics study.

4. Update and discussion of the next w/s – 14 – 21 November 2005, Imperial

KL described motivation for proposal circulated before the meeting. LR commented that the process would clearly evolve and that muon physics should be mentioned. KL to update text and redistribute for comment.

Action 4.1: KL: Update w/s #1 first bulletin and re-circulate.

It was agreed that a short document would be generated at the end of each workshop.

5. AoB
