Possible Evidence of Time Variation of Weak Interaction Constant from Double Beta Decay Experiments

Abstract

A comparison is made of the probability of the process of two neutrino double beta decay for 82Se in direct (counter) and geochemical experiments. It is shown that the probability is systematically lower in geochemical experiments, which characterize the probability of ββ(2v) decay a few billion years ago. The experimental data for 130Te are also analyzed. It is shown that geochemical measurements on young minerals give lower values of T 1/2(130Te) and T 1/2(82Se) as compared to measurements on old minerals. It is proposed that this could be due to a change in the weak interaction constant with time. Possibilities of new, precise measurements performed with the aid of counters and geochemical experiments are discussed.KeywordsBeta DecayTrack DetectorFundamental ConstantNewtonian Gravitation ConstantLarge Number HypothesisThese keywords were added by machine and not by the authors.
