摘要:

本文从静态球对称线元的角度研究了具有Higgs势的标量-张量引力理论中黑洞解的本质性质。在已有结果的基础上,引入级数展开法求解不含和含Higgs场质量的场方程,得到了Reissner-Nordström-like和Schwarzschild黑洞解.利用状态方程参数、标量场激发和测地线运动,详细讨论了黑洞解和弱场极限解的物理意义.裸奇点的外观也讨论了一起依赖的黑洞视野上的字段激发,这是自己依赖于压力项,有效地筛选质量条款。一个可能的连接到平坦的旋转曲线以下的相互作用与标量场也提出了在弱场的重力极限,连同讨论的动力学效应的标量场和压力项的质量。

英文摘要:

We study the quintessential properties of the Black Hole solutions in a scalar--tensor theory of gravity with Higgs potential in view of the static and spherically symmetric line element. In view of our earlier results, Reissner--Nordström-like and Schwarzschild Black Hole solutions are derived with the introduction of a series-expansion method to solve the field equations without and with Higgs field mass. The physical consequences of the Black Hole solutions and the solutions obtained in the weak field limit are discussed in detail by the virtue of the equation-of-state parameter, the scalar-field excitations and the geodesic motion. The appearance of naked singularities is also discussed together with the dependence of Black Hole horizons on the field excitations, which are themselves dependent on pressure terms which effectively screen the mass terms. A possible connection to flat rotation curves following the interaction with the scalar field is also presented in the weak field limit of gravity, together with a discussion of dynamical effects of scalar fields and pressure terms on mass.
