1Beyond q13
Gabriela Barenboim
APS Neutrino Study Reactor Working Group
2We have just closed
annus mirabilis
- K2K Indication of neutrino oscillations in a
250 km - First Results from KamLAND Evidence for
Reactor - Nobel Prize award to R. Davis Jr. and M. Koshiba
- WMAP First year Wilkinson microwave anysotropy
probe observations determination of
cosmological parameters - Precise measurements of the solar neutrino D/N
and seasonal variations in Super-Kamiokande - SNO salt phase results Measurements of the
Total - Sloan Digital Sky Survey Cosmological
parameters
3It is indeed a gift
4Let's not blow it !!
5The evidence
6We obtained
Dm223 (1.3 3.0) 10-3 eV2 sin2 (2 q23) gt .9
atmospheric
Dm212 (5.8 8.4) 10-5 eV2 tan2 (q12) lt .52
solar
7The next step
- the mass hierarchy
-
- the connecting angle q13
- the CP violating phase d
8Is there any physics beyond q13 ?
9Yes !!!!
10Yes !!!!
Measure or bound neutrino magnetic moment
11Yes !!!!
Measure or bound neutrino magnetic moment Search
for oscillation effects of sterile neutrinos
12Yes !!!!
Measure or bound neutrino magnetic moment Search

Measure sin2 qw (check NuTeV result)
13Yes !!!!

tests (reactor vs solar neutrinos)
17WE KNOW "FOR SURE" THAT CPT
IS VIOLATED IN NATURE !!!
18WE KNOW "FOR SURE" THAT CPT
IS VIOLATED IN NATURE !!!
We have measured a cosmological constant that is
different from zero
19Beware of CPT !
20To keep in mind
- Low Homestake rate ?
- Absence of the upturn of the spectrum ?
21SNO Spectrum ?
Turn down at low energies ?
22To keep in mind
- Low Homestake rate ?
- Absence of the upturn of the spectrum ?
Next KamLAND data release still some shift in
Dm2 is not excluded.
23There is a rich non-q13 program which might help
make the q13 program happen.
24- Measure or bound neutrino magnetic moment
- Search for oscillation effects of sterile
neutrinos - Measure sin2 qw (check NuTeV result)
- FINeSE at a reactor ?
- Anything interesting about structure functions ?
- What about supernovas ?
- CPT tests (reactor vs solar neutrinos)
25Let's not sit on it !
