Akerib, DS, Alsum, S, Araújo, HM et al. (95 more authors) (2020) Search for two neutrino double electron capture of 124Xe and 126Xe in the full exposure of the LUX detector. Journal of Physics G: Nuclear and Particle Physics, 47 (10). 105105. ISSN 0954-3899
Abstract
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 27769.5 kg-days. No evidence of a signal was observed, allowing us to set 90% C.L. lower limits for the half-lives of these decays of 2.0 × 1021 years for 124Xe and 1.9 × 1021 years for 126Xe.
