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. Using the neutral current (NC), elastic scattering, and charged current reactions and… Expand
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. For charged current events, assuming an undistorted 8B spectrum, the night minus day rate is… Expand

Limits on WIMP cross-sections from the NAIAD experiment at the Boulby Underground Laboratory
The NAIAD experiment (NaI Advanced Detector) for WIMP dark matter searches at the Boulby Underground Laboratory (North Yorkshire, UK) ran from 2000 until 2003. A total of 44.9 kg × years of data… Expand
First limits on nuclear recoil events from the ZEPLIN I galactic dark
We report first results from the ZEPLIN I dark matter detector, based on measurement of scintillation pulse shapes in a liquid xenon target of 3.2 kg fiducial mass. Neutron calibration shows nuclear… Expand
On pursuit curves
Recently, several papers [2–4, 6] have been published concerning a pursuit problem which was apparently first posed explicitly by Leonardo da Vinci and which may have been present in earlier thinking… Expand
Improved dark matter limits from pulse shape discrimination in a low background sodium iodide detector at the Boulby mine
Abstract We report new limits on nuclear scattering events resulting from Galactic dark matter in the form of hypothetical weakly interacting massive particles. By pulse shape analysis of 6 months'… Expand
The NAIAD experiment for WIMP searches at Boulby mine and recent results
Abstract The NAIAD experiment (NaI Advanced Detector) for weakly interacting massive particle (WIMP) dark matter searches at Boulby mine (UK) is described. The detector consists of an array of… Expand
Zinc sulphide scintillator with faster decay
Silver-activated, nickel-killed zinc sulphide phosphor, of the type normally used in scintillation counters, is found to emit at least 11% of its light at times greater than 100 mu s. Increasing the… Expand
