The neutrinoless double beta (0νββ) decay experiment GERDA has taken 21.6 kg·yr of data in Phase I. A comprehensive background model is presented. The half life of the two-neutrino double beta decay of Ge-76 has been determined as (1.926 ± 0.094) x 10 21 yr. No indication for a 0νββ signal has been found. A lower limit at 90% C.I. on 0νββ half life of 1.85 x 10 25 yr from GERDA data alone and 2.86 x 10 25 yr from the combination with data of past HPGe experiments has been derived using Bayesian…

Status and prospects of searches for neutrinoless double beta decay
The simultaneous beta decay of two neutrons in a nucleus without the emission of neutrinos (called neutrinoless double beta decay) is a lepton number violating process which is not allowed in the
Conversion of experimental half-life to effective electron neutrino mass in 0nubetabeta decay
The Germanium Detector Array (GERDA) collaboration will be searching for neutrinoless double beta decay of {sup 76}Ge. As a result it will measure the half-life T{sub 1/2} of this rare process; or at

TLDR
The combined results from KamLAND-Zen and EXO-200 give T(1/2)(0ν)>3.4×10(25) yr at 90% C.L., which corresponds to a Majorana neutrino mass limit of <(120-250) meV based on a representative range of available matrix element calculations.
