衰变暗物质发射光子的偏振

Polarization of photons emitted by decaying dark matter

W. Bonivento, D. Gorbunov, M. Shaposhnikov, A. Tokareva

摘要:

通过研究星系和星系团的光子谱,可以寻找辐射衰变的暗物质。我们探讨是否可以通过研究发射光子的偏振态来约束暗物质的性质。从量子力学的基本原理出发,证明了对称暗物质的模型不能被光子的极化所分辨。然而,我们发现由狄拉克费米子组成的非对称暗物质是圆偏振光子的来源,这就需要对光子态进行实验测定。

英文摘要:

Radiatively decaying dark matter may be searched through investigating the photon spectrum of galaxies and galaxy clusters. We explore whether the properties of dark matter can be constrained through the study of a polarization state of emitted photons. Starting from the basic principles of quantum mechanics we show that the models of symmetric dark matter are indiscernible by the photon polarization. However, we find that the asymmetric dark matter consisted of Dirac fermions is a source of circularly polarized photons, calling for the experimental determination of the photon state.
