论文摘要
Dama协作报告了每年调制的速率，其相位与暗物质引起的信号兼容。我们指出，如果通过从固定日期开始从固定日期开始减去大约年平均值，而不是及时连续的背景，则可以根据数据计算出的残差来分析数据，甚至可以模拟年度调制。在最极端的情况下，Dama报告的年度调制的幅度和阶段可以被解释为该速率的十年型增长。通过对可用数据的详细研究，这种可能性似乎有些分歧，但不能安全排除。通常，降低或增加的速率可以部分降低或增强真正的年度调制。可以通过查看达马总率的全日制依赖性，迄今未明确发表的全职依赖性来阐明问题。
The DAMA collaboration reported an annually modulated rate with a phase compatible with a Dark Matter induced signal. We point out that a slowly varying rate can bias or even simulate an annual modulation if data are analyzed in terms of residuals computed by subtracting approximately yearly averages starting from a fixed date, rather than a background continuous in time. In the most extreme case, the amplitude and phase of the annual modulation reported by DAMA could be alternatively interpreted as a decennial growth of the rate. This possibility appears mildly disfavoured by a detailed study of the available data, but cannot be safely excluded. In general, a decreasing or increasing rate could partially reduce or enhance a true annual modulation, respectively. The issue could be clarified by looking at the full time-dependence of the DAMA total rate, not explicitly published so far.
