直接暗物质探测数据与晕无关的比较

Halo independent comparison of direct dark matter detection data

Paolo Gondolo, Graciela B. Gelmini

摘要:

我们扩展了Fox,Liu和Weiner的Halo-independent方法,以包括具有任意能量依赖性的能量分辨率和效率,使其更适合于实验来展示他们的结果。然后,我们比较测量和上限的直接检测低质量($\sim10$ GeV)弱相互作用的大质量粒子与自旋无关的相互作用,包括上限的年度调制幅度从CDMS合作。我们发现,同位旋对称的耦合受到严格的限制,无论是由XENON 100和CDMS的界限,和同位旋违反耦合仍然是可能的,在最低的能量,而较高的能量CoGeNT箱与CDMS调制约束的张力仍然存在。我们发现CRESST II信号与DAMA和CoGeNT的调制信号不兼容。

英文摘要:

We extend the halo-independent method of Fox, Liu, and Weiner to include energy resolution and efficiency with arbitrary energy dependence, making it more suitable for experiments to use in presenting their results. Then we compare measurements and upper limits on the direct detection of low mass ($\sim10$ GeV) weakly interacting massive particles with spin-independent interactions, including the upper limit on the annual modulation amplitude from the CDMS collaboration. We find that isospin-symmetric couplings are severely constrained both by XENON100 and CDMS bounds, and that isospin-violating couplings are still possible at the lowest energies, while the tension of the higher energy CoGeNT bins with the CDMS modulation constraint remains. We find the CRESST II signal is not compatible with the modulation signals of DAMA and CoGeNT.
