  1. 28. Long baseline experiment and proton decay search using Hyper-K
    Prof. Masashi Yokoyama (University of Tokyo)
    22/08/2012, 13:55
    I will review the physics potential of a long baseline experiment using J-PARC neutrino beam and Hyper-K, and proton decay search in Hyper-K.

  3. 27. Towards Reduced Neutrino Flux & Interaction Uncertainties for a J-PARC to Hyper-K Experiment
    Dr Mark Hartz (University of Toronto/York University)
    22/08/2012, 14:40
    The Hyper-K letter of intent discusses the physics potential to measure delta_cp by a J-PARC to Hyper-K long baseline experiment assuming systematic errors for the signal and background that are controlled at the 5% level. Reducing uncertainties in neutrino flux and interaction modeling will be crucial to achieve 5% uncertainties. The T2K experiment, which uses the J-PARC neutrino beam, an...

  4. 46. Irreducible Cross-Section Uncertainties for Electron Neutrino Appearance?
    Kevin McFarland (University of Rochester)
    22/08/2012, 15:00
    The usual strategy for controlling systematic uncertainties due to neutrino interactions in oscillation experiments is to use the same beam, or data from other experiments, to constrain those uncertainties. In this brief discussion, I point out a few limitations in this technique that may be problematic for oscillation physics in the high precision era, and I will suggest some possible remedies.

  5. 49. Atmospheric Neutrino Oscillations at Hyper-Kamiokande
    Dr Roger Wendell (ICRR)
    22/08/2012, 15:20
    Recently experimental measurements of reactor, atmospheric, and solar neutrinos have provided an increasingly clear picture of neutrino oscillations. However, several open issues including the nature of the neutrino mass hierarchy, the octant of $\theta_{23}$, and whether or not neutrinos are CP-violating, remain. Atmospheric neutrinos are capable of addressing these questions due to the...

  7. 42. Solar neutrinos and supernova burst neutrinos at Hyper-Kamiokande
    Dr Yusuke Koshio (Kamioka observatory, ICRR, Univ. of Tokyo)
    22/08/2012, 16:25
    n this presentation, the sensitivity of solar neutrinos is discussed. In the case of shallow place, the most serious background will be spallation products induced from cosmic ray muons. How much reduce background by improving an analysis method will be estimated. Using this result, the requirement for the solar neutrino physics, such as the constraint to delta-m-square_21, is discussed. The...

  8. 29. Supernova neutrino astronomy with Hyper-Kamiokande
    Dr Shunsaku Horiuchi (CCAPP, Ohio State University)
    22/08/2012, 16:50
    The diffuse supernova neutrino background (DSNB) is the faint glow of MeV neutrinos from distant core-collapse supernovae. It has not been detected yet, but the Super-K upper limit on the flux of electron antineutrino is very close to modern predictions. Hyper-K is expected to detect dozens of DSNB neutrinos yearly. In addition, Hyper-K will open a new window of neutrinos from core collapses...

  9. 45. Dark Matter Sensitivity Studies
    Dr Carsten Rott (CCAPP / Ohio State University)
    22/08/2012, 17:15
    Hyper-Kamiokande will have a tremendous potential for the detection of neutrino signals from dark matter annihilations. The talk will give an overview of analysis methods and dark matter detection channels relevant for Hyper-K. The talk will conclude by giving dark matter sensitivities and by pointing out specific instrumental details that will help to optimize the physics potential for Hyper-K.
