Distillation of Liquid Xenon to Remove Krypton (2008)

Abe, K., Hosaka, J., Iida, T., Ikeda, M., Kobayashi, K., Koshio, Y., ...

A high performance distillation system to remove krypton from xenon was constructed, and a purity level of Kr/Xe = $\sim 3 \times 10^{-12}$ was achieved. This development is crucial in facilitating...

Solar neutrino measurements in Super-Kamiokande-II (2008)

Cravens, J. P., Abe, K., Iida, T., Ishihara, K., Kameda, J., Koshio, Y., ...

The results of the second phase of the Super-Kamiokande solar neutrino measurement are presented and compared to the first phase. The solar neutrino flux spectrum and time variation as well as...

Scintillation yield of liquid xenon at room temperature (2008)

Ueshima, K., Abe, K., Iida, T., Ikeda, M., Kobayashi, K., Koshio, Y., ...

The intensity of scintillation light emission from liquid xenon at room temperature was measured. The scintillation light yield at 1 deg. was measured to be 0.64 +/- 0.02 (stat.) +/- 0.06 (sys.) of...

Search for matter-dependent atmospheric neutrino oscillations in Super-Kamiokande (2008)

Abe, K., Hayato, Y., Iida, T., Ikeda, M., Kameda, J., Koshio, Y., ...

We consider ν_μ→ν_τ oscillations in the context of the mass varying neutrino (MaVaN) model, where the neutrino mass can vary depending on the electron density along the flight path of the...

Observation of the anisotropy of 10 TeV primary cosmic ray nuclei flux with the Super-Kamiokande-I detector (2007)

Guillian, G., Hosaka, J., Ishihara, K., Kameda, J., Koshio, Y., Minamino, A., ...

The relative sidereal variation in the arrival direction of primary cosmic ray nuclei of median energy 10 TeV was measured using downward, through-going muons detected with the Super-Kamiokande-I...

Deuteron and Anti-deuteron Production in $e^+ e^-$ Collisions at the Z Resonance (2006)

Schael, S, Aubert, B, Zalipska, J, Yoshida, M, Yoo, J, Yokoyama, M, ...

Deuteron and anti-deuteron production in Z decays has been observed in the ALEPH experiment at LEP. The production rate of anti-deuterons is measured to be 5.9+-1.8+-0.5 10^-6 per hadronic Z decay in...

Limits on the neutrino magnetic moment using 1496 days of Super-Kamiokande-I solar neutrino data (2004)

Ashie, Y, Fukuda, S, Fukuda, Y, Ishihara, K, Itow, Y, ...

A search for a nonzero neutrino magnetic moment has been conducted using 1496 live days of solar neutrino data from Super-Kamiokande-I. Specifically, we searched for distortions to the energy...

The recent results of solar neutrino measurements in Super-Kamiokande (2003)

Koshio, Y.

The results of solar neutrino data from the first phase of Super-Kamiokande are presented. Super-Kamiokande can measure not only the solar neutrino flux but also its energy spectrum and its time...

Search for nu(e) from the sun at Super-Kamiokande-I (2003)

Fukuda, S, Fukuda, Y, Ishitsuka, M, Itow, Y, Kajita, T, ...

We present the results of a search for low energy nu(e) from the Sun using 1496 days of data from Super-Kamiokande-I. We observe no significant excess of events and set an upper limit for the...

Search for supernova relic neutrinos at Super-Kamiokande (2003)

Morii, M, Fukuda, S, Fukuda, Y, Ishitsuka, M, Itow, Y, ...

A search for the relic neutrinos from all past core-collapse supernovae was conducted using 1496 days of data from the Super-Kamiokande detector. This analysis looked for electron-type antineutrinos...

Indications of neutrino oscillation in a 250 km long-baseline experiment (2003)

Aoki, S, Bhang, H, Casper, D, Choi, J H, ...

The K2K experiment observes indications of neutrino oscillation: a reduction of nu(mu) flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in...
