14年1月30日木曜日 US-Japan Research Program in HEP
• Long successful history • In Fermilab • CDF, KTeV, DONUT, SciBooNE, etc. • For neutrinos • BNL E734, FNAL E745, DONUT, SciBooNE, etc.
• Based on the long and good relationship between US and Japan, we consider to propose collaborative research subjects for accelerator neutrino experiments.

14年1月30日木曜日 Neutrino Physics in US and Japan
• In Japan (at KEK/J-PARC and Kamioka) • T2K, KamLAND, Super-K, Hyper-K and Neutrino Detector R&D including Lq. Ar TPC development • In US (at FNAL) • MiniBooNE, MINOS, MINERvA, MicroBooNE, NOvA and LBNE
• Both US and Japan have high power and high energy proton accelerators (FNAL MI and KEK J- PARC) with intense neutrino beam lines. Those facilities are great advantages for us to explore neutrino physics.

14年1月30日木曜日 Physics from accelerator ν experiments • Precision measurements of neutrino oscillation parameters: 2 2 θ12, θ13, θ32, Δm32 , Δm12 • Precision measurements of neutrino cross sections: CC-QE, NC-EL, CC-1π, NC-π0, DIS, etc..
• Search for CP violation: measurement of δCP and/or model independent test of CPV (ν vs anti-ν). • Determination of Mass hierarchy • Search for New physics: sterile neutrinos and unexpected phenomena
• Performance of accelerators, neutrino beams, and detectors, and improvements of analysis and simulation techniques are crucial to advance the neutrino physics.
