Sudbury Neutrino Observatory Results
A. B. McDonald Physics Department Queen's University Kingston, Ontario CANADA K7L 3N6 For the SNO Collaboration e-mail [email protected] Abstract The Sudbury Neutrino Observatory uses 1000 tonnes of heavy water in an ultraclean Cherenkov detector situated 2 km underground in Ontario, Canada to study neutrinos from the Sun and other astrophysical sources. The Charged Current (CC) reaction on deuteri...
متن کاملRecent Results from the Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory (SNO) measures both the flux of the electron-type neutrinos and the total flux of all active flavours of neutrinos originating from the Sun. A model-independent test of neutrino flavour transformation was performed by comparing these two measurements. In 2002, this flavour transformation was definitively demonstrated. In this talk, results from these measurement...
متن کاملFirst Results from the Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory (SNO) is a water imaging Čerenkov detector. Utilising a 1 kilotonne ultra-pure D2O target, it is the first experiment to have equal sensitivity to all flavours of active neutrinos. This allows a solar-model independent test of the neutrino oscillation hypothesis to be made. Solar neutrinos from the decay of B have been detected at SNO by the charged-current (CC)...
متن کاملSolar Neutrino Results from the Sudbury Neutrino Observatory
We describe here the measurement of the flux of neutrinos created by the decay of solar B by the Sudbury Neutrino Observatory (SNO). The neutrinos were detected via the charged current (CC) reaction on deuterium and by the elastic scattering (ES) of electrons. The CC reaction is sensitive exclusively to νe’s, while the ES reaction also has a small sensitivity to νμ’s and ντ ’s. The flux of νe’s...
متن کاملNeutrino Observations from the Sudbury Neutrino Observatory
a The first neutrino observations from the Sudbury Neutrino Observatory are presented from preliminary analyses. Based on energy, direction and location, the data in the region of interest appear to be dominated by 8 B solar neutrinos, detected by the charged current reaction on deuterium and elastic scattering from electrons, with very little background. Measurements of radioactive backgrounds...
