Testing Oscillations

In the design of any neutrino oscillation experiment, you want to measure something (x) which will be different if oscillations exist;

e.g. Nevent , R=NC/CC, Nkink

In general, x = x(,m2)

often x~ x(P12)

interaction discovery

• DONUT - Fermilab beam dump experiment published 2000

• expected from Ds decay

• 203 events in photographic emulsion • See 4 events, expect 4.1 • Background from charm & hadrons

How Long is Long?

Definitions of “Long-Baseline”(my use is for accelerator based experiments)

• Webster - (long - measuring much, or more than usual, from end-to-end in space or time)

• Practical - Off site

• Useful (Beam) - The distance from the source to the detector is much greater than the length of the decay pipe.

• Useful (Physics) - L >> E/m2

Superbeams

need $ on powerful proton drivers (0.5-4MW)

e.g. BNL to Homestake (SD) or WIPP (New Mexico)

JHF to Super-Kamiokande

Fermilab to Soudan/Homestake/WIPPmore protons yield more ’schallenges: target cooling; ground water radiation;

accelerator and power costs; e backgrounds

reach in sin22

Conclusion

The world is one in which there has been much recent progress ( mass; mixing).

New insights are expected soon (KamLAND, Borexino, K2K, MINOS)

Another round of experiments at “superbeams” and factories will tell us more.
