The search for majoron emission in xenon-136 and two-neutrino double-beta decay of xenon-134 with the Enriched Xenon Observatory
Despite neutrino oscillation experiments firmly establishing neutrinos have non-zero mass, the absolute mass scale is unknown. Moreover, it's unknown whether the neutrino is distinguishable from its antiparticle. The most promising approach for measuring the neutrino mass scale and answering the …

Measurement of the double beta decay half-life of ^{100}Mo to the 0^{+}_{1} excited state, and ^{48}Ca to the ground state in the NEMO 3 experiment
… tunnel which runs between France and Italy. If neutrinoless double beta decay is observed it will prove the neutrino is a Majorana particle and may potentially become the most sensitive method of measuring the absolute neutrino mass. It would also have huge implications for not only particle …

Searches for new physics at MiniBooNE : sterile neutrinos and mixing freedom
… different from that allowed by standard, three neutrino oscillations, as determined by solar and atmospheric neutrino experiments. This search was motivated by the LSND experimental observation of an excess of F/e events in a 1,1 beam which was found compatible with two-neutrino oscillations at …

Radioactive source measurements in a liquid xenon time projection chamber
… is a rare nuclear process that can occur in two different modes. The first is known as the two-neutrino double beta decay, which is a second-order weak interaction process and has already been observed in several nuclei. The second one is called neutrino less double beta decay. This is a …

A measurement of the atmospheric neutrino flux and oscillation parameters at the Sudbury Neutrino Observatory
… of their direction of travel through the Sudbury Neutrino Observatory. Based on simulations and previous measurements, muons with a zenith angle of 1 < cos([theta]zenith) < 0:4 are selected as atmospheric neutrino-induced muons. A two-neutrino analysis of these events agrees with the oscillation …

Search for neutrinoless double beta decay of ¹¹⁶Cd and ⁸²Se and calorimeter simulations for the SuperNEMO experiment
… 3.75 kg• y were used to measure the half-life of two-neutrino double beta decay (2[nu][beta][beta]) to the ground states of ¹¹⁶Sn and ⁸²Kr and to place a lower limit on the neutrinoless double becay decay (0[nu][beta][beta]) to the same ground states. Under the single-states dominance hypothesis, …

Searching for Reactor Antineutrino Flavor Oscillations with the Double Chooz Far Detector
… presents results from a search for reactor antineutrinoₑ flavor oscillations using the Double Chooz Far Detector. The search was performed by observing the rate and energy spectrum of antineutrinoₑ interacting via Inverse Beta Decay in a Gd-doped liquid scintillator detector, and comparing the …

Double-Beta Decay of 96Zr and Double-Electron Capture of 156Dy to Excited Final States
<p>Two separate experimental searches for second-order weak nuclear decays to excited final states were conducted. Both experiments were carried out at the Kimballton Underground Research Facility to provide shielding from cosmic rays. The first search is for the two-neutrino double-beta decay of …

Double-Beta Decay of <super>150</super>Nd to Excited Final States
<p>An experimental study of the two-neutrino double-beta (2νββ) decay of <super>150</super>Nd to various excited final states of <super>150</super>Sm was performed at Triangle Universities Nuclear Laboratory (TUNL). Such data provide important checks for theoretical models used to predict 0νββ …

A search for the Higgs boson in H->WW->lvlv with 8.2 fb-1
… boson to WW production in the final state of two charged leptons (e, μ) and two neutrino final state resulting from in pp collisions at √ s = 1.96 TeV. The data collected by the CDF II detector at the Tevatron collider at Fermilab, corresponds to an integrated luminosity of 8.2 fb−1. This …
