  2. 5. HK sensitivity with T2K systematic treatment
    Dr Motoyasu Ikeda (Kyoto University)
    21/06/2013, 10:40
    The sensitivity of CP measurement using J-PARC beam shown in Hyper-K LOI is calculated with fixed theta_23 and delta m^2_32, and the treatment of systematic uncertainty is very simple. To validate the LOI sensitivity, I will show the sensitivity obtained by fitting 4 oscillation parameters (delta_CP, theta_13, theta_23, and delta m^2_32) with more realistic treatment of the systematic...

  3. 7. Systematic uncertainties in long-baseline neutrino oscillation experiments
    Dr Szymon Manecki (VirginiaTech)
    21/06/2013, 11:00
    The CP violating effect in the $\nu_\mu\rightarrow \nu_e$ oscillation probability is suppressed with respect to the CP-conserving contribution. Therefore, systematic uncertainties affecting the signal at long baseline oscillation experiments are extremely relevant for the CP violation searches. We will present a phenomenological analysis showing the possible impact that systematic errors may...

  4. 26. Near Detector Considerations
    Prof. Francesca Di Lodovico (Queen Mary, University of London)
    21/06/2013, 11:20
    Some considerations regarding the near detectors are presented. With a focus on the physics needs for the Hyper-Kamiokande-based long baseline experiment, the expected future performance, aging and needed refurbishment for the current T2K ND280 detector and possible future ideal near detector setups.

  5. 3. A New Proposal for a Tokai to Hyper-K Near Detector
    Dr Michael Wilking (TRIUMF)
    21/06/2013, 13:20
    In order to maximize the physics potential of a projected 10 year beam running period, systematic uncertainties at the 2% level are required, and the largest source of systematic uncertainty is projected to be from uncertainties on neutrino interaction cross sections. This new near detector proposal aims to significantly reduce the dependence of T2HK measurements on a priori knowledge of...

  6. 21. An application of the neutrino oscillation to geophysics : Study of the Earth's core composition using atmospheric neutrino
    Dr Akimichi Taketa (Earthquake Research Institute)
    21/06/2013, 13:40
    Neutrino oscillations inside matter are sensitive to the electron density. On the other hand, neutrino absorption is sensitive to the mass density. The mass density distribution of the Earth's core is also inferred from seismic tomography. Therefore, neutrino oscillation can be used for a probe to determine the average atomic mass ratio A/Z of the Earth's core by comparing with the mass...

  9. 41. Search for the spin-independently coupling WIMP captured in the Sun/the Earth in Hyper-Kamiokande
    Ms koun choi (nagoya university)
    21/06/2013, 14:50
    WIMP searches using the captured WIMP by terrestrial bodies are characterized by whether the scattering is spin-independent (in which case the WIMP couples to the mass in the nucleus) or spin-dependent (in which case the WIMP couples to the spin of the nucleus). For spin-dependent coupling case, Hyper-K solar analysis is expected to have strongest sensitivity among currently proposed detectors...
