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 oscillation results are statistically consistent with the first phase and do not show spectral distortion. The time-dependent flux measurement of the combined first and second phases coincides with the full period of solar cycle 23 and shows no correlation with solar activity. The measured {sup 8}B total… 

Solar results from Super-Kamiokande

The recent results of solar neutrino measurement from the Super-Kamiokande (SK) are presented. SK has four phases (SK-I to IV) since starting the operation in 1996. Thanks to the background

Solar neutrino results from Super-Kamiokande

Recent results of the Super-Kamiokande (SK) solar neutrino measurements are presented. The main goal of SK’s solar analysis is to observe the MSW effect, i.e. a solar neutrino energy spectrum

Super-Kamiokande (SK), a 50 kton water Cherenkov detector in Japan, is observing neutrinos and searching for proton decay and dark matter. The installation of new front-end electronics in 2008 marks

Atmospheric neutrino oscillation analysis with subleading effects in Super-Kamiokande I, II, and III

We present a search for nonzero {theta}{sub 13} and deviations of sin{sup 2{theta}}{sub 23} from 0.5 in the oscillations of atmospheric neutrino data from Super-Kamiokande I, II, and III. No

First evidence of pep solar neutrinos by direct detection in Borexino

The observed solar neutrinos in the 1.0-1.5 MeV energy range represents the first direct evidence of the pep neutrino signal and the strongest constraint of the CNO solar neutRino flux to date.



Measurement of the total active 8B solar neutrino flux at the Sudbury Neutrino Observatory with enhanced neutral current sensitivity.

The Sudbury Neutrino Observatory has precisely determined the total active (nu(x)) 8B solar neutrino flux without assumptions about the energy dependence of the nu(e) survival probability. The

Electron energy spectra, fluxes, and day-night asymmetries of 8B solar neutrinos from measurements with NaCl dissolved in the heavy-water detector at the Sudbury Neutrino Observatory

Results are reported from the complete salt phase of the Sudbury Neutrino Observatory experiment in which NaCl was dissolved in the {sup 2}H{sub 2}O (''D{sub 2}O'') target. The addition of salt

Measurement of neutrino oscillation with KamLAND: evidence of spectral distortion.

The observed energy spectrum disagrees with the expected spectral shape in the absence of neutrino oscillation at 99.6% significance and prefers the distortion expected from nu (e) oscillation effects.

Standard neutrino spectrum from 8B decay.

A numerical representation of the best-fit (standard-model) neutrino spectrum, as well as two extreme deviations from the standard spectrum that represent the total (experimental and theoretical) effective {plus_minus}3{sigma} deviations are given.

Measurement of day and night neutrino energy spectra at SNO and constraints on neutrino mixing parameters.

The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates, and a global solar neutRino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.

Measurement of the Solar Electron Neutrino Flux with the Homestake Chlorine Detector

The Homestake Solar Neutrino Detector, based on the inverse beta-decay reaction νe +37Cl →37Ar + e-, has been measuring the flux of solar neutrinos since 1970. The experiment has operated in a stable

Direct evidence for neutrino flavor transformation from neutral-current interactions in the Sudbury Neutrino Observatory.

Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported, providing strong evidence for solar nu(e) flavor transformation.

Measurement of the solar neutrino capture rate with gallium metal. III:2002-2007

The Sun produces its energy by the nuclear fusion of four protons into an α particle, chains of reactions that yield two positrons and two neutrinos. Since these lowenergy neutrinos are weakly
