CRESST- II对动量相关非对称暗物质的限制
Limits on momentum-dependent asymmetric dark matter with CRESST-II
摘要：
在直接暗物质搜索中，通常的假设是只考虑暗物质粒子的自旋相关或自旋无关散射。然而，特别是在轻暗物质粒子$\mathcal{O}(\mathrm{GeV/c^2})$的模型中，携带额外的动力传递$q^2$的运营商可以成为主导。一个这样的模型的基础上不对称的暗物质已被调用，以克服日震学的差异和指示被发现的粒子与首选质量为3 $\mathrm{GeV/c^2}$和横截面的$10^{-37} \mathrm{cm^2}$。CRESST-II实验使用基于$\mathrm{CaWO_4}$的低温探测器来搜索由暗物质粒子引起的核反冲，该实验的最新数据被用来约束这些动量依赖模型。所使用的探测器的核反冲的低能量阈值为307 eV，允许我们排除上述建议的最佳拟合值。
英文摘要：
The usual assumption in direct dark matter searches is to only consider the spin-dependent or spin-independent scattering of dark matter particles. However, especially in models with light dark matter particles $\mathcal{O}(\mathrm{GeV/c^2})$, operators which carry additional powers of the momentum transfer $q^2$ can become dominant. One such model based on asymmetric dark matter has been invoked to overcome discrepancies in helioseismology and an indication was found for a particle with preferred mass of 3 $\mathrm{GeV/c^2}$ and cross section of $10^{-37} \mathrm{cm^2}$. Recent data from the CRESST-II experiment, which uses cryogenic detectors based on $\mathrm{CaWO_4}$ to search for nuclear recoils induced by dark matter particles, are used to constrain these momentum-dependent models. The low energy threshold of 307 eV for nuclear recoils of the detector used, allows us to rule out the proposed best fit value above.
