Title: Recent developments in the theory of double beta decay

We report results of a novel calculation of phase space factors for 2νβ{sup +}β{sup +}, 2νβ{sup +}EC, 2νECEC, 0νβ{sup +}β{sup +}, and 0νβ{sup +}EC using exact Dirac wave functions, and finite nuclear size and electron screening corrections. We present results of expected half-lives for 0νβ{sup +}β{sup +} and 0νβ{sup +}EC decays obtained by combining the calculation of phase space factors with IBM-2 nuclear matrix elements.
