Apologies from J.Olsen
Marcello introduces the meeting mentioning the still
unofficial replies from the IRC on the Physics Case. The
feedback from IRC is positive and few questions will be
soon sent. The central point is to try to make sharper
the discovery potential cases with some explicit demonstration
on the need of 10**36 luminosity. Some example
- LFV in the tau decays (from discovery point of view)
probably coupling at least two decay modes.
- CP violation in D0 sector and evenutally on tau.
- use of the snowmass points to to show that effects are
visible on flavour observable and that flavour parameters
can be (precisely) measured
Private discussions between some people present at the meeting
with the IRC and the IRC members confirm the positive attitude
of the IRC and the need of more work mentionned above.
Marcello discussed about the needs of involving more people in this
effort. SC committed to adding new people to the responsibles of the
Physics chapter of the CDR (Marco, Tim and Achille) Riccardo Faccini
and Jim Olsen. Both accepted to help. Marcello remind that him,
David Hitlin, Mike Roney and David Asner volonteer to help in
the organisation of Valencia meeting.
Discussion started (involving all) on the organisation of the Working
Groups for Valencia meeting. Conclusions are that these working groups
are the place where the answers to the IRC are prepared (with some work)
and where we could try to go further and to add new topics which have
been not really discussed in the CDR and not explicitely asked by IRC
(ex: spetroscopy)
Possible groups with some specifications and with names of people who
volonteer to contribute are given below.
- tau physics M. Roney, A. Lusiani, M. Giorgi, P. Bernabeu,
D. Hitlin...
[we should ask if the theorists who worked on the tau chapter
for the CDR (Isidori & Paradisi) would like to be involved.]
For LVF at least two channels have to be studied with more care,
probably tau-> mu gamma and tau--> mu mu mu.
On the other hands we should work on
-ACP in tau decay for a particular mode. Plot of the ACP
-Anomalous and charge magnetic moment in tau decay
-EDM
to eventually demonstrate the need for polarized beams.
Here a discussion started, yet not conclusive, on the needs of splitting
this group in two groups. A proposal suggests the splitting of the
groups more along the lines of "LFV" and "physics with polarized
beams"
- Charm physics. Centered on CP violation I. Bigi, D. Asner +
students..
In CDR the CP violation in D0 mixing was just touched. More work is
needed on it. David said he can involve PHD students to work on it.
Ikaros will participate to the workshop.
- Phenomenological group. M. Ciuchini, T. Gershon, A. Stocchi...
Refinements of the CDR material trying to pointing out better the
discovery potential as a function of the luminosity (for instance
on MSSM + generic SUSY breaking terms scenario..)
Work on Snowmass points as asked by the IRC. Marco will try to contact
theorists to join this group. Sofar DeltaF=2 measurements were used,
DeltaF=1 measurements should be added. For this group, the expertise
on b--> s gamma is essential, mainly to see if we can gain in precision
on the measurement of the Branching fraction by lowering the cut on the
E(gamma). Experts should be involved. John Walsh has been contacted.
This group should study many other measurements (and more realistically)
[B-->tau nu, B-->Xs ll....].
- Spectroscopy. A. Polosa, Santorelli, D. Bernard...
This issue had a little space on CDR and have been not discussed at
the meeting with the IRC. Neverthless experts beleive that an increase
of the stat. by a factor 100 could be very important for clarifying the
present puzzles and in future for potential discoveries. It has been
also advokated the interest of running at the thresholds of the new
discovered resonnaces. This is worthwhile to study being a unique
specificity of the SFF.
Finally on the initiative of M. Morandini an activity on tools
needed for superb is about starting and a meeting will take place
at SLAC on Thr. 6th december, during the Babar coll. meeting.
There was some discussion over who should lead the tools group.
Either one of R.Faccini, T.Gershon, J.Olsen, A.Stocchi,
or M.Morandin, or someone else.
Conveners have to be soon choosen.
A letter to Babar management will be soon written and sent to
let them know of this new activity and of the Valencia meeting.
Valencia meeting is scheduled from 7th to 15th of January.
Fernando and Valencia friends promise a web page soon.
It has been decided to have regular meeting on Friday at (17.30) (Rome-time)
and to keep all the information posted on the superb web page.
It was decided that Marcello will call the meetings and Achille will
keep minutes that will be circulated.
Marcello and Achille
There are minutes attached to this event.
