Cosmogenic Backgrounds to 0νββ in EXO-200
200 Collaboration, J. B. Albert, D. J. Auty +84
As neutrinoless double-beta decay experiments become more sensitive and intrinsic radioactivity in detector materials is reduced, previously minor contributions to the background m…
Search for Majorana neutrinos with the first two years of EXO-200 data
200 Collaboration, J. B. Albert, D. J. Auty +91
Many extensions of the Standard Model of particle physics suggest that neutrinos should be Majorana-type fermions, but this assumption is difficult to confirm. Observation of neutr…
Spectroscopy of Ba and Ba deposits in solid xenon for barium tagging in nEXO
B. Mong, S. Cook, T. Walton +73
Progress on a method of barium tagging for the nEXO double beta decay experiment is reported. Absorption and emission spectra for deposits of barium atoms and ions in solid xenon m…
Search for Neutrinoless Double-Beta Decay in Xe with EXO-200
M. Auger, D. J. Auty, P. S. Barbeau +75
We report on a search for neutrinoless double-beta decay of Xe with EXO-200. No signal is observed for an exposure of 32.5 kg-yr, with a background of ~1.5 x 10^{-3} /(kg y…
Measurements of the ion fraction and mobility of alpha and beta decay products in liquid xenon using EXO-200
J. B. Albert, D. J. Auty, P. S. Barbeau +82
Alpha decays in the EXO-200 detector are used to measure the fraction of charged and daughters created from alpha and beta decays, respectiv…
An improved measurement of the 2νββ half-life of Xe-136 with EXO-200
J. B. Albert, M. Auger, D. J. Auty +94
We report on an improved measurement of the 2νββ half-life of Xe-136 performed by EXO-200. The use of a large and homogeneous time projection chamber allows for the precise esti…
