Comment: Lower bound for the neutrinoless double-beta decay half-life of 76Ge: T1/2 > 1.9 × 1025 y at 90% CL. The corresponding upper bound for the effective neutrino mass is <m> < 0.35 eV. (C.G.).

Why is the Conclusion of the GERDA Experiment not Justified ?, Hans Volker Klapdor-Kleingrothaus, Irina V. Krivosheina, Sergey N. Karpov, Phys.Part.Nucl.Lett. 10 (2013) 704-709, arXiv:1308.2524.
Klapdor's claim for the observation of the neutrinoless double beta-decay of Ge-76. Analysis and corrections, Kirpichnikov I.V., arXiv:1006.2025, 2010.
The evidence for the observation of 0nu beta beta decay: The identification of 0nu beta beta events from the full spectra, H. V. Klapdor-Kleingrothaus, I. V. Krivosheina, Mod. Phys. Lett. A21 (2006) 1547-1566.
From the abstract: Two different methods of pulse shape analysis have been used to select potential $0\nu\beta\beta$ events from the $\gamma$-background. Both methods lead to selections of events at $Q_{\beta\beta}$ with almost no $\gamma$-background. The observed line at $Q_{\beta\beta}$ is identified as a $0\nu\beta\beta$ signal. It has a confidence level of more than $6\sigma$.

Data acquisition and analysis of the 76Ge double beta experiment in Gran Sasso 1990-2003, H.V. Klapdor-Kleingrothaus, A. Dietz, O. Chkvorez, I.V. Krivosheina, Nucl. Instrum. Meth. A522 (2004) 371-406, arXiv:hep-ph/0403018.
From the abstract: the confidence level for the neutrinoless signal has been improved.
From the article: we confirm, with 4.2σ (99.9973% c.l.) probability, our claim from 2001 [2-8], [Go], [2-13], [Go], [Go] of first evidence for the neutrinoless double beta decay mode.
Using the nuclear matrix element from Refs.[Go,Go], we conclude from the half-life given above the effective mass $\langle m \rangle$ to be $\langle m \rangle = (0.2-0.6) \, \mathrm{eV}$ (99.73% c.l.) with the best value of 0.4 eV.
Allowing conservatively for an uncertainty of the nuclear matrix element of ±50%, the range for the effective mass may widen to $\langle m \rangle = (0.1-0.9) \, \mathrm{eV}$ (99.73% c.l.).

Comment: Evidence in favor of the observation of neutrinoless double-beta decay of 76Ge is claimed, with T1/2 = (0.8-18.3) × 1025 y at 95% CL and best value T1/2 = 1.5 × 1025 y. The corresponding effective neutrino mass is <m> = 0.11-0.56 eV and best value <m> = 0.39 eV. (C.G.).
