DAMA-LIBRA年调制的一个可检验的常规假设

A testable conventional hypothesis for the DAMA-LIBRA annual modulation

David Nygren

摘要:

DAMA-LIBRA协作组(D-L)观测到的年度调制信号可以合理地解释为宇宙射线μ子穿透探测器而沉积在NaI(Tl)晶体中的能量的结果。延迟脉冲的近似能量范围内的利益已被观察到作为一个续集的能量沉积的UV照射。同样的行为可以合理地预期发生的能量沉积的任何来源的电离或激发。D-L可以通过在当前数据中的调制能量范围内搜索μ子事件和脉冲之间的时间相关性,并通过在足够低的温度下重新运行阵列来测试这一假设,从而冻结现象。

英文摘要:

The annual modulation signal observed by the DAMA-LIBRA Collaboration (D-L) may plausibly be explained as a consequence of energy deposited in the NaI(Tl) crystals by cosmic ray muons penetrating the detector. Delayed pulses in the approximate energy range of interest have been observed as a sequel to energy deposited by UV irradiation. The same behavior may be reasonably expected to occur for energy deposited by any source of ionization or excitation. D-L can test this hypothesis by searching for time correlations between muon events and pulses in modulation energy range in current data, and by renewed operation of the array at a sufficiently low temperature that would freeze out the phenomenon.
