在本文中，我们考虑非常弱的相互作用和超轻标量和赝标量暗物质的候选人。我们证明了量子引力对此类模型具有重要影响，并且单重标量场和伪标量场的质量必须大于eV。然而，如果对它们进行测量，它们的质量可能会轻得多，甚至和地球一样轻。因此，暗物质领域中新规范力的存在可以通过原子钟或量子传感器实验来探测。
In this paper we consider very weakly interacting and ultra light scalar and pseudoscalar dark matter candidates. We show that quantum gravity has important implications for such models and that the masses of the singlet scalar and pseudoscalar fields must be heavier thaneV. However, if they are gauged, their masses could be much lighter and as light as. The existence of new gauge forces in the dark matter sector can thus be probed by atomic clocks or quantum sensors experiments.
