Double Beta Decay

  title={Double Beta Decay},
  author={Steven R. Elliott and P. R. O. Vogel},
We review recent developments in double-beta decay, focusing on what can be learned about the three light neutrinos in future experiments. We examine the effects of uncertainties in already measured neutrino parameters and in calculated nuclear matrix elements on the interpretation of upcoming double-beta decay measurements. We then review a number of proposed experiments. PACS numbers: 11.30.Fs, 14.60.-z, 23.40.-s
