[en] The India’s TIN (TIN.TIN) detector is under development in the search of neutrinoless double-β decay (0νββ) using 90% enriched 124Sn isotope as the target mass. This detector will be housed in the upcoming underground facility of the India-based Neutrino Observatory. We present the most important experimental parameters that would be used in the study of required sensitivity for the TIN.TIN experiment to probe the neutrino mass hierarchy. The sensitivity of the TIN.TIN detector in the presence of sole two neutrino double-β decay (2νββ) background is studied at various energy resolutions. The most optimistic and pessimistic scenario to probe the neutrino mass hierarchy at 3σ sensitivity level and 90% CL are discussed. (author)

[en] Thanks to the excellent energy resolution, high efficiency and versatility, bolometric detectors are primed for the search of neutrinoless double-beta decay (0νDBD). The most advanced bolometric experiment, CUORE, is studying the 0νDBD of "1"3"0Te using a 741 kg array of TeO_2 crystals. CUORE points to a 90% CL sensitivity on the half-life of 0νDBD of 9.5 × 10"2"5 yr in 5 yr, corresponding to an upper limit on the neutrino Majorana mass of 50–130 meV. This sensitivity will allow to touch, but not to explore, the region corresponding to the inverted hierarchy mass scenario. In this document I present the status of CUORE and the possible upgrades of the bolometric technology in view of a next generation experiment.

[en] Beta-decay half-lives have been calculated by a microscopic theory for nuclei with 6< or =Z< or =114 between the line of beta-stability and the neutron drip line. The calculated half-lives are independent of the present uncertainties of nuclear mass formulas. The accuracy of the predictions is considerably improved over that of an earlier prediction based on a ''gross theory'' of beta decay

[en] The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be accurately calculated if experiments are to reach their full potential. Theorists have been working on the problem for a long time but have recently stepped up their efforts as ton-scale experiments have begun to look feasible. Here we review past and recent work on the matrix elements in a wide variety of nuclear models and discuss work that will be done in the near future. Ab initio nuclear-structure theory, which is developing rapidly, holds out hope of more accurate matrix elements with quantifiable error bars. (review)
