摘要:

\textbf{T}和\textbf{IN} dia的\textbf{TIN}(TIN.TIN)探测器正在开发中,用于使用90%富集的$^{124}$ Sn同位素作为目标质量来寻找无中微子双$β$衰变(0 $νββ$)。该探测器将被安置在基于\textbf{I} ndia的\textbf{N} eutrino \textbf{O}观测站的地下设施中。我们提出了最重要的实验参数,将用于研究所需的灵敏度为TIN。TIN实验探测中微子质量等级。本文研究了TIN探测器在不同能量分辨率下对仅有的两个中微子双$β$衰变(2 $νββ$)背景的灵敏度。在3 $σ$灵敏度水平和90% C. L.也进行了讨论。

英文摘要:

\textbf{T}he \textbf{IN}dia's \textbf{TIN} (TIN.TIN) detector is under development in the search for neutrinoless double-$β$ decay (0$νββ$) using 90\% enriched $^{124}$Sn isotope as the target mass. This detector will be housed in the upcoming underground facility of the \textbf{I}ndia based \textbf{N}eutrino \textbf{O}bservatory. 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 (2$νββ$) decay background is studied at various energy resolutions. The most optimistic and pessimistic scenario to probe the neutrino mass hierarchy at 3$σ$ sensitivity level and 90\% C.L. is also discussed.
