摘要

作为一种工作假设，有人认为 "正常 "和暗物质的相互作用只能是[公式：见正文]-和[公式：见正文]-违反。实现这一观点的一种方法是考虑暗物质中的时间反转不是由反单元算子而是由单元算子实现的。这说明了在具有扩展对称群的复时空背景下，这种情况是如何自然发生的。

T-violation and the dark sector

It is argued, as a working hypothesis, that “normal” and dark matter interactions can only be [Formula: see text]- and [Formula: see text]-violating. One way to implement this idea is to consider that time reversal in dark matter is implemented, not by an antiunitary operator, but by an unitary operator. It is shown how this occurs naturally in the context of complex spacetime with an extended symmetry group.

期刊介绍： This letters journal, launched in 1986, consists of research papers covering current research developments in Gravitation, Cosmology, Astrophysics, Nuclear Physics, Particles and Fields, Accelerator physics, and Quantum Information. A Brief Review section has also been initiated with the purpose of publishing short reports on the latest experimental findings and urgent new theoretical developments.
