Oscillation Parameter Dependence

4

- 𝜹𝒄𝒑: ±27% effect at T2K for 𝜽𝟐𝟑 = 𝟒𝟓𝒐

- 𝛿]^~−_+ : enhances 𝑃 𝜈# → 𝜈5 , suppresses 𝑃 𝜈# → 𝜈5

- 𝛿]^~+_+ : suppresses 𝑃 𝜈# → 𝜈5 , enhances 𝑃 𝜈# → 𝜈5

- Mass hierarchy: ±10% effect at T2K- Normal: enhances 𝑃 𝜈# → 𝜈5 , suppresses 𝑃 𝜈# → 𝜈5- Inverted: suppresses 𝑃 𝜈# → 𝜈5 , enhances 𝑃 𝜈# → 𝜈5

- 𝐬𝐢𝐧𝟐 𝟐𝜽𝟏𝟑 and 𝐬𝐢𝐧𝟐 𝜽𝟐𝟑- Leading terms- “Octant” dependence; whether 𝜃+. > 45g, 𝜃+. < 45g , or 𝜃+. = 45g

J-PARC and Neutrino Beamline

5

- 30 GeV proton beam generated by J-PARC Main Ring (MR) directed to the graphite target- Secondary pions collected and focused by the magnetic horns

- 𝜈 beam: 𝜋j → 𝜇j + 𝜈# (Forward horn current)- 𝜈 beam: 𝜋l → 𝜇l + 𝜈#(Reverse horn current)

- Uses off-axis method to make the spectrum peak at 600 MeV- Expected oscillation maximum at L=295 km

T2K Near Detectors

6

- On-axis INGRID and off-axis ND280

ND280- Scintillators and water targets- Consists of trackers, calorimeters,

and muon detectors- UA1 magnet (0.2T)- Tracks the neutrino prior to

oscillationsINGRID- Scintillators and iron targets- measure neutrino beam direction

and stability

T2K-II: a Proposed Extension of the T2K Experiment

22

T2K to T2K-II

- Approved T2K statistics 7.8×10+1 POT, expected around 2020- 1st stage of J-PARC main ring power supply upgrade approved

- Aiming for > 1 MW beam power (currently 420 kW)- T2K-II extends T2K run to 20×10+1 POT on the time scale of 2026- Requires accelerator and beam-line upgrade to reach 1.3 MW
