我们报告的CUORICINO实验的最终结果。2003年至2008年期间运行,总接触量为19.75公斤。由于Te-130,CUORICINO能够将Te-130 0 nu β β半衰期的下限设定为2.8 x 10(24)年(90% C. L)。这里报告的限制包括系统不确定性的影响,详细检查的文件。中微子马约拉纳质量的相应上限在300-710 meV范围内,具体取决于所采用的核矩阵元评估。(C)2011 Elsevier B. V.保留所有权利。
We report the final result of the CUORICINO experiment. Operated between 2003 and 2008, with a total exposure of 19.75 kg . y of Te-130, CUORICINO was able to set a lower bound on the Te-130 0 nu beta beta half-life of 2.8 x 10(24) years at 90% C.L. The limit here reported includes the effects of systematic uncertainties that are examined in detail in the paper. The corresponding upper bound on the neutrino Majorana mass is in the range 300-710 meV, depending on the adopted nuclear matrix element evaluation. (C) 2011 Elsevier B.V. All rights reserved.
