14. CP study

Masashi Yokoyama (University of Tokyo)

14/01/2013, 09:50

An update of CP sensitivity study will be given.

12. Considerations for a Near Detector for the Tokai-to-HK experiment

Mr Hirohisa A. Tanaka (University of British Columbia/Institute of Particle Physics)

14/01/2013, 10:35

I will discuss considerations for the design and desired capabilities for a near detector for the long-baseline component of the Hyper-Kamiokande physics program (Tokai-to-HK). My comments will focus mainly on potential incremental upgrades to the existing ND280 off-axis detector for T2K, but will include thoughts on more substantial upgrades.

10. Off-Axis Detectors as Direct Measurements of Neutrino Energy Reconstruction

Prof. Kevin McFarland (University of Rochester), Dr Mark Hartz (University of Toronto and York University)

14/01/2013, 10:55

Uncertainties in neutrino energy reconstruction in quasi-elastic scattering due to nuclear effects may be a significant systematic uncertainty for oscillations measurements at Hyper-K. We investigate the possibility of directly measuring these misreconstructions in a model-independent way with a series of off-axis near detectors.

30. Atmospheric Neutrino Sensitivity Studies

Roger Wendell (ICRR)

14/01/2013, 11:15

This talk will present an update of the expected sensitivity to neutrino oscillations at Hyper-K after corrections to the analysis method and updates of the global value of theta_13.

21. Muon charge identification with gadolinium-loaded water

Dr Christopher Mauger (LANL)

14/01/2013, 11:30

A novel approach to muon charge-identification is described. The approach uses the neutron-capture signal available in the presence of gadolinium. Applications to atmospheric neutrino studies are discussed.

23. Improvement of event selection of proton decay searches

Shunichi Mine (UCI)

14/01/2013, 13:25

This talk will present studies toward the improvement of proton decay event selection at HK using shape information from the signal and background distributions instead of pure counting methods used in proton decay searches at SK thus far. Emphasis will be on the p->e+pi0 mode.

17. Improvement of proton decay analysis in p-->nu-bar+K^+

Dr Makoto Miura (Kamioka Observatory, ICRR, University of Tokyo)

14/01/2013, 13:40

Physics Potential

The proton decay mode, p--> nu-bar+K^+ is favored by SUSY-GUTs and it is an important analysis for Hyper-K. Recently, there have been several improvement in the alaysis. I will discuss how much sensitivity of Hyper-K will be improved by these improvements.

26. Spallation background

Prof. Yasuo Takeuchi (Dept. of Physics, Grad. School of Science, Kobe Univ.)

14/01/2013, 13:55

An estimation of spallation background in HK will be reported.

31. Solar neutrinos and supernova burst neutrinos at Hyper-Kamiokande

Dr Yusuke Koshio (Kamioka observatory, ICRR, Univ. of Tokyo)

14/01/2013, 14:15

The sensitivity of solar neutrinos is discussed in this presentation. The modification from the previous meeting will be updated back ground rate from spallation, therefore, the results will be more realistic. Another topics is supernova burst neutrinos. This will be more precise than the discussion in the previous meeting, especially, a correlation with another observation such as gravitational wave.

9. SRN search with HK

Dr Takatomi Yano (Okayama Univ.)

14/01/2013, 14:35

In this presentation, SRN sensitivity at HK, with and without Gd option, will be discussed.

22. Neutrinographic imaging of the earth

Akimichi Taketa (Earthquake Research Institute)

14/01/2013, 15:20

Absorption neutrinography utilizes very high energy neutrinos with energies above 10 TeV to measure the nucleon density inside the earth whereas oscillation neutrinography measures the electron density by observing the MSW effect. Two independent physical quantities might provide new geophysical information, e.g., isotope ratio, to us. In this talk, a recent attempt to use atmospheric...
