2
Atmospheric and Solar Neutrino Measurements (M. Smy)
3
MiniBooNE oscillation analysis (Curioni) Optical model tuned Beam uncertainties <~20% HE box open. Note: tight cuts used. Not representative of final statistics.
4
Final results from K2K (Kaneyuki) e 1 event 1.7 B.G
5
MINOS results from 1 st year of NuMI
6
Neutrinos on JEOPARDY (US quiz show)
7
NOvA (Howcroft) 20-25 kt detector 80% active Located off NuMI beam axis July’06 P5 Preliminary report: “We recommend the start of the NOvA neutrino oscillation experiment… This experiment is complementary to other neutrino experiments on a world-wide basis and represents the next step for the U.S. in a phased international program.” Technical design review: Jan-Feb. 2007. Start data taking end 2010 - 2011
8
NOvA (Howcroft) NOvA provides data needed to plan next step
9
FNAL-BNL joint study on long baseline neutrinos (Bishai) Study to evaluate options for US program after NOvA Wide band beam FNAL to DUSEL? 2 nd NOvA detector at 2 nd oscillation maximum …?
10
Water cherenkov measurements at 2 km for T2K (M. Smy) 2 km controls systematics for disappearance measurement
11
The LqAr TPC for the 2 km station (Badertscher) Proposed 100 ton LqAr to complement H2O Prototype dewar has been designed Safety issues being studied ARGONTUBE to demonstrate 5 m drift distances
12
T2KK (Okumura) Summary of 2 nd workshop, Seoul July‘06
13
CNGS and OPERA (De Lellis) CNGS underway! Events seen in OPERA 5 Target bricks being installed. ~1000 bricks/day Final sample: 20 events 1 background
14
Performances of beta beams at (Mezzetto) Updated study of beat-beam CERN to Frejus Improved cross-section and detector response models ~x3 improvement in sensitivity over previous study Most likely due to improved energy resolution
15
Alternating ions in a Beam to solve degeneracies (Fernadez-Martinez) 500 kton water Cherenkov,L=650 km If 13 is large alternating B and Li at first peak and Ne and He at second peak reduces 8 fold degeneracy to two fold degeneravcy Reactor experiment can break remaining degeneracy Has sensitivity to mass hierarchy
16
LAGUNA (A. Rubbia) Large Apparati for Grand Unification and Neutrino Astrophysics The common challenges
17
Double CHOOZ (Kaplan) 2008? Improvement in statistics Improvement in systematics Ultimate sensitivity down to 0.03 Funding secured in Europe. US pursuing NSF/DOE funding
18
Angra neutrino project: safeguards applications: (Anjos) Collaboration: Brazil/US/France/Italy Monitoring nuclear activity with antineutrinos Sites identified at Angra reactor
19
Magnetised Iron Detector (Cervera Villanueva) Improved kinematic cuts Improved simulation at low energy
20
Optimization of a neutrino factory (Huber) Repeat L-E optimization for standard NF setup Having detectors at ~4000 km and 7000 km enhances CP reach and solves degeneracies sin 2 2 13 CP reach Mass hierarchy
