“…6. 18. For 10 mTorr of helium gas and 1 mTorr of xenon gas, according to the data the ion signal fades with τ > 10 3 s, while the simulation suggests the signal should fade with a time constant of τ ∼ 1 s. We believe the difference arises from the fact that the simulation neglects the long range contributions of the ion-ion coulombic potential and of the long range induced dipole potential.…”

Single Ion Trapping for the Enriched Xenon Observatory

In the last decade, a variety of neutrino oscillation experiments have established that there is a mass difference between neutrino flavors, without determining the absolute neutrino mass scale. The Enriched Xenon Observatory for neutrinoless double beta decay (EXO) will search for the rare decays of xenon to determine the absolute value of the neutrino mass. The experiment uses a novel technique to minimize backgrounds, identifying the decay daughter product in real time using single ion spectroscopy. Here, we describe single ion trapping and spectroscopy compatible with the EXO detector. We extend the technique of single ion trapping in ultrahigh vacuum to trapping in xenon gas. With this technique, EXO will achieve a neutrino mass sensitivity of m ν .010 eV.v vi

“…Collaboration [27], this result is criticized [28] and shall be checked by the forthcoming experiment. It is believed that that the next generation 0νββ experiments, with the sensitivity of m ee being up to 0.01 eV [29], will open the window to not only the absolute neutrino mass scale but also the Majorana-type CP violation.…”

In this paper we investigate the parallel texture structures containing texture zeros in charged lepton mass matrix M l and cofactor zeros in neutrino mass matrix M ν . These textures are interesting since they are related to the Z n flavor symmetries. Using the weak basis permutation transformation, the 15 parallel textures are grouped as 4 classes (class I,II,III and IV) with the matrices in each class sharing the same physical implications.Under the current experimental data, the class I, III with inverted mass hierarchy and class II with normal mass hierarchy are phenomenologically acceptable. The correlations between some important physical variables are presented, which are essential for the model selection and can be text by future experiments. The model realization is illustrated by means of Z 4 × Z 2 flavor symmetry.

“…In 2002, Elliott and 25 other physicists said as much in a letter 3 to Modern Physics Letters A, the journal that had published the result. They weren't convinced, for instance, that the Heidelberg researchers had correctly attributed some of the peaks to bismuth-214 in the rocks surrounding the lab and in the detector components.…”
