论文摘要
考虑使用偏振核靶标测试费米金暗物质的非标准性质的可能性。假定在载体，轴向，标量和张量相互作用的情况下，传入的暗物质散布在极化核上。假定标量和张量耦合为副本。根据有关暗物质极化和后坐力核自旋的测量的假设，对各种类型的测量设置进行了测试。特别是，我们解决了在理论上可能的情况下发现和区分影响的问题，在理论上可能的情景中，在各种极化矢量之间将三产物混合在一起，即传入的暗物质和后坐力核的动量出现在横截面中。它们的存在将表明在两极分化的暗物质核散射中违反时间逆转对称性的可能性。我们的考虑是独立于模型的，并在非相关的暗物质和后退核极限中进行。
Possibility of using the polarized nucleus target for testing the non-standard properties of fermionic dark matter is considered. It is assumed that the incoming dark matter scatters on the polarized nuclei in the presence of vector, axial, scalar and tensor interactions. The scalar and tensor couplings are assumed to be complex numbers. Various types of measurement settings are tested depending on the assumptions regarding dark matter polarization and measurement of the recoil nucleus spin. In particular we address the question of finding and distinguishing effects of theoretically possible scenarios in which mixed triple products among various polarization vectors, the momenta of incoming dark matter and of recoil nucleus appear in the cross section. Their presence would indicate the possibility of time reversal symmetry violation in the polarized dark matter-nucleus scattering. Our considerations are model-independent and carried out in the non-relativistic dark matter and recoiled nucleus limit.
