Abstract / Description of output
Two-neutrino double electron capture is a process allowed in the standard model of particle physics. This rare decay has been observed in 78Kr, 130Ba
and more recently in 124Xe. In this publication we report on the search for this
process in 124Xe and 126Xe using the full exposure of the large underground
xenon (LUX) experiment, in a total of 277 69.5 kg-days. No evidence of a
signal was observed, allowing us to set 90% C.L. lower limits for the halflives
of these decays of 2.0 × 1021 years for 124Xe and 1.9 × 1021 years for
126Xe.
