关于可能存在超光速粒子的几种几何模型的评述
Comments on the Hypothesis about Possible Class of Particles Able to Travel Faster then Light: Some Geometrical Models
摘要：
最近，L。冈萨雷斯-梅斯特斯，分析。为此，引入了几种不同Lorentziann结构物质共存于同一流形上的一般几何模型，并计算了两种特殊情况下宇宙学参考系中的局域能量密度。结果表明，在这两种情况下，局域能量密度都是正的，因此这种模型确实可以描述宇宙学暗物质。然而，在宇宙学模型或致密天体模型的构建过程中，可能会出现一些问题。此外，该模型的最简单的推广导致了一些变体的矢量张量引力理论与更好的参考系，这与观测相矛盾。
英文摘要：
The hypothesis about possible existence of new class of particles able to travel faster then light as a source of dark matter, recently formulated by L. Gonzalez-Mesters, is analyzed. To this end the general geometrical model for several kinds of matter with different Lorentziann structures coexisting on the same manifold is introduced and the local energy density in cosmological reference frame is calculated in two particular cases. It is shown that the local energy density is positive in both considered cases and hence such models really may describe cosmological dark matter. Nevertheless, some problems may appear during the construction of the cosmological models or the models of the compact objects. Moreover, the simplest generalization of the model lead to some variants of vector-tensor theory of gravitation with preferable reference frame which contradict to observations.
