摘要:

15个月的累积CoGeNT数据的年度调制,弱相互作用大质量粒子(WIMP)相互作用的预测签名的迹象进行检查。目前可用的数据支持存在一个调制组件的来源不明,与参数初步兼容的星系晕组成的轻质量WIMP。非优化估计产生的调制的统计意义为~2.8西格玛,有限的短期曝光。

英文摘要:

Fifteen months of cumulative CoGeNT data are examined for indications of an annual modulation, a predicted signature of Weakly Interacting Massive Particle (WIMP) interactions. Presently available data support the presence of a modulated component of unknown origin, with parameters prima facie compatible with a galactic halo composed of light-mass WIMPs. Unoptimized estimators yield a statistical significance for a modulation of ~2.8 sigma, limited by the short exposure.
