$^{130}$ Te $2νββ$衰变half-life的CUORE-0背景分析和评价

CUORE-0 background analysis and evaluation of $^{130}$Te $2νββ$ decay half-life

Davide Chiesa

摘要:

CUORE是一个热测量实验,将寻找$^{130}$ Te的无中子双β衰变。CUORE-0是一个类似CUORE的塔,在2013年至2015年期间运行,以测试CUORE实验的性能。在这一过程中,我们提出的模型的结果,解开和量化的背景源,结合形成CUORE-0的能量谱。我们使用详细的基于Geant 4的模拟和贝叶斯拟合算法来重建实验数据,并评估背景源的活动。该分析的直接结果是测量$^{130}$ Te $2νββ$的衰变半衰期,我们对此进行了初步评估。

英文摘要:

CUORE is a bolometric experiment that will search for the Neutrinoless Double Beta decay of $^{130}$Te. CUORE-0 is a single CUORE-like tower that was run between 2013 and 2015 to test the performance of the CUORE experiment. In this proceeding we present the results of the model developed to disentangle and quantify the background sources that combine to form the CUORE-0 energy spectrum. We use detailed Geant4-based simulations and a Bayesian fitting algorithm to reconstruct the experimental data and evaluate the activities of the background sources. A direct outcome of this analysis is the measurement of the $^{130}$Te $2νββ$ decay half-life, of which we provide a preliminary evaluation.
