利用直接探测鉴别暗物质候选者

Discriminating dark matter candidates using direct detection

G. Belanger, E. Nezri, A. Pukhov

摘要:

我们研究了在各种新的粒子物理模型与暗物质候选人的自旋相关和自旋无关的直接检测率的预测。我们表明,质子和中子的自旋独立和自旋相关的振幅的测定原则上可以区分不同的候选人的暗物质到几个歧义。我们强调的重要性,使测量与不同的自旋相关的敏感探测器材料和需要显着提高探测器的灵敏度。新的有色粒子的交换对弹性散射截面有显著贡献的情况通常是最难识别的,LHC应该给出这种散射是否与直接检测相关的指示。

英文摘要:

We examine the predictions for both the spin dependent and spin independent direct detection rates in a variety of new particle physics models with dark matter candidates. We show that a determination of both spin independent and spin dependent amplitudes on protons and neutrons can in principle discriminate different candidates of dark matter up to a few ambiguities. We emphasize the importance of making measurements with different spin dependent sensitive detector materials and the need for significant improvement of the detector sensitivities. Scenarii where exchange of new coloured particles contributes significantly to the elastic scattering cross sections are often the most difficult to identify, the LHC should give an indication whether such scenarii are relevant for direct detection.
