Neutrinos in CHIPP
Allan Clark
Neuchâtel Meeting 21-22 June
2004
Plan
•
Welcome
•
What and why CHIPP?
•
A word of caution - a bad strategy is worse than no
strategy - physics motivation
•
The present - why do we need a strategy?
•
Reaching a CH strategy for the period 2005-18
What and why CHIPP? (1)
1.
2.
3.
4.
Institutes in CH involved in
research and/or teaching in
particle physics
Coordinate a cohesive
research strategy for
research, based on physics
motivation
Coordinate and enhance
teaching in particle physics in
Switzerland (doctoral school
etc)
Why is this needed?
CH wants to be at fore-front
of main experimental
developments, but resources
limited. Future initiatives may
be CHIPP (not institutional)
initiatives
An initial CHIPP initiative has been a
study:
“Particle Physics in Switzerland:
Status and Outlook of Research and
Education”
What and why CHIPP? (2)
Recommendation 1 - LHC
The physics exploitation of the LHC is the first priority of the particle physics
programme in Switzerland. CHIPP recommends that resources are provided to
exploit the physics data of the LHC and to cover the maintenance and operation
costs of Swiss participation in the LHC experiments in an optimal way
Recommendation 4 – Approved Neutrino Physics Programme
CHIPP recommends that the necessary funding be provided for the maintenance,
operation and physics exploitation of the OPERA and ICARUS neutrino
experiments using the CNGS beam for at least 5 years from 2006.
Recommendation 5 – Neutrino Physics and the Near Future
The neutrino programme (J-PARC neutrino) in Japan should allow significantly
improved measurements in the neutrino sector from about 2008 for at least 5
years. CHIPP recommends that an active and visible contribution by Swiss
groups should be investigated
Recommendation 6 – the interface with cosmology
CHIPP recommends an urgent scientific reflection by the physics community in
Switzerland on the key fundamental questions such as dark matter, dark energy
and space-time that are within the domain of particle physics.
Recommendation 7 – accelerator R&D
CHIPP recommends that the Swiss delegation to CERN actively encourages
CERN to fund the necessary accelerator R&D towards demonstrating the
feasibility of a multi-TeV e+e- linear collider (CLIC technology) by approximately
2007. CHIPP also recommends that CERN should adequately fund the R&D
studies now necessary to allow a decision on the construction of a high intensity
proton source following the completion of the LHC.
A word of caution
1. Tendencies: protagonists of long term programmes forget the wider
outlook and often the other priorities - wisdom is an asset
2. A 10-year strategy is only useful if there is a common consensus of
physics merit/opportunity. No strategy is better than a bad strategy.
A good strategy is better than both.
3. We talk here of physics results, not longer term accelerator research
C. Hill, HCP 2004
The present - a vibrant programme (1)
1. What is the 15-year instrumental benefit of the existing programme
What is the expected contribution to the neutrino outlook from the existing
programme?
The present - a vibrant programme (2)
1. Guiding principle: any mid-term commitment would normally involve the
definition and construction of part of the detector, and the exploitation of
that detector for the full collaboration
The next question?
sin q13?
Where? USA, Japan? Europe?
Enormous range of excellent
activities, next step is bigger,
must be done in international
context
Reaching a CH strategy for the period 2005-18
1.
Guiding principle: CHIPP wants to play a visible and respected role in the next generation
of lepton flavor studies
2.
The real purpose of this workshop
3.
•
because of the interest, many workshops, development plans -US, JP, EU
•
measurements of sin q13 and improved precision on Dm213, Dm223 are the immediate
goal, then ….
Any collaborative CHIPP physics strategy/program can only succeed if all are behind it,
and if it is physics-motivated (no territorial interests)
•
To what degree is a common programme achievable/desirable, does it exist
•
If so, is it a CHIPP program with participation throughout CHIPP institutes
A personal comment:
-
any discussion of a Generation 3 superbeam, or neutrino factory, is of enormous
interest/ importance, but I believe beyond the major conclusions of this meeting
-
any such development programme should not have adverse effect on CURRENT
2005-18 programme. Within Switzerland, funding for accelerator research should
be from PSI, CERN, EU budgets (which is important)
-
If consensus reached on programme to 2018, priority will be to find funding for it
- CHIPP’s job
Another personal comment:
-
I am looking forward to the result of this workshop, and thanks again to our
friends outside Switzerland
