摘要:

对于任意引力耦合常数,利用具有平坦标积的自共轭哈密顿量,数值计算了Schwarzschild引力场中基本自旋半粒子的非衰减束缚态.希尔伯特条件g_{00} >0导致一个边界条件,使得狄拉克粒子的电流密度矢量的分量在“事件视界“附近为零。在小的耦合常数值下,能谱接近于类氢谱。根据这项研究的结果,我们可以假设存在一种新型的坍缩,而这种坍缩不存在霍金辐射机制。从宇宙学的观点来看,如果引力耦合常数的值很小,α <<1,那么这种新型的无辐射残馀星只能通过引力来显现。因此,它们是“暗物质“载体的良好候选者。在大范围的可接受质量中,可能存在一种新的具有假设的WIMP粒子质量的类星体,在宇宙膨胀的许多场景中,它们被视为“暗物质“的代表。这项研究的结果可能导致重新审视标准宇宙学模型中有关宇宙演化和双星与周围物质相互作用的一些概念。

英文摘要:

Nondecaying bound states of elementary spin-half particles are validated and calculated numerically for the Schwarzschild gravitational field using a self-conjugate Hamiltonian with a flat scalar product for any value of the gravitational coupling constant. Hilbert condition g_{00}>0 leads to a boundary condition such that components of the vector of current density of Dirac particles are zero near the "event horizon". At small values of the coupling constant, the energy spectrum is close to the hydrogen-like spectrum. Based on the results of this study, we can assume that there exists a new type of collapsars, for which the Hawking radiation mechanism is not present. From the standpoint of cosmology, if the value of the gravitational coupling constant is small, alpha<<1, the new type of nonradiating relict collapsars can manifest itself only through gravitation. Thus, they are good candidates for the role of "dark matter" carriers. In the wide range of admissible masses, there can exist collapsars of a new type with the masses of hypothesized WIMP particles, which are treated as representatives of "dark matter" in numerous scenarios of the expansion of the universe. The results of this study can lead to revisiting some concepts of the standard cosmological model related to the evolution of the universe and interaction of collapsars with surrounding matter.
