Half-life 0${{\boldsymbol \nu}}$ double-$\beta$ decay INSPIRE search

In most cases the transitions (Z,A)$~\rightarrow~$(Z+2,A) $+~2{{\mathit e}^{-}}$ to the 0${}^{+}$ ground state of the final nucleus are listed. We also list transitions that decrease the nuclear charge (2${{\mathit e}^{+}}$, ${{\mathit e}^{+}}$ CC and double EC) and transitions to an excited state of the final nucleus (0${}^{+}_{i}$, 2${}^{+}$, and 2${}^{+}_{i}$). In the following Listings only the best or comparable limits for the half-lives of each transition are reported and only those with about T$_{1/2}>10^{23}$ years that are relevant for particle physics.

Supersedes GANDO 2013A. The sensitivity is 5.6 10${}^{25}$ yr.
24  ARNOLD 2015 use the NEMO-3 tracking calorimeter with 34.3 kg yr exposure to determine the limit of 0${{\mathit \nu}}{{\mathit \beta}}{{\mathit \beta}}$-half life of ${}^{100}\mathrm {Mo}$. Supersedes {ARNOLD 2005A} and BARABASH 2011A.

35  AALSETH 2002B limit is based on 117 mol$\cdot{}$yr of data using enriched Ge detectors. Background reduction by means of pulse shape analysis is applied to part of the data set. Reported limit is slightly less restrictive than that in KLAPDOR-KLEINGROTHAUS 2001 However, it excludes part of the allowed half-life range reported in KLAPDOR-KLEINGROTHAUS 2001B for the same nuclide. The analysis has been criticized in KLAPDOR-KLEINGROTHAUS 2004B. The criticism was addressed and disputed in AALSETH 2004 .
36  KLAPDOR-KLEINGROTHAUS 2001 is a continuation of the work published in BAUDIS 1999 . Isotopically enriched Ge detectors are used in calorimetric measurement. The most stringent bound is derived from the data set in which pulse-shape analysis has been used to reduce background. Exposure time is $35.5~$kg$~$y. Supersedes BAUDIS 1999 as most stringent result.
