decay /de·cay/ (de-ka´) 1. the decomposition of dead matter. 2. the process of decline, as in aging. beta decay disintegration of the nucleus of an unstable radionuclide in which the mass number is unchanged, but atomic number is changed by 1, as a result of emission of a negatively or positively charged (beta) particle. tooth decay dental caries. beta decay, a type of radioactivity that results in the emission of beta particles, either electrons or positrons.

] beta decays [4], CKM unitarity (assumes conserved vector current, CKM unitarity, and values of |[V. Another class of effects leads to gamma ray asymmetries from beta decays of polarized nuclei produced by interactions of the beam with materials upstream of the hydrogen target. The entire experiment is inside a room-sized tank that chills it to 160 kelvins to increase the incidence of beta decays as the gas moves along. |
