标题： Dyonic Non-Abelian Black Holes

摘要： 我们研究爱因斯坦-杨-米尔斯-希格斯理论中的静态球对称磁电黑洞。 对于磁非阿贝尔黑洞而言，磁电非阿贝尔黑洞的存在域相对于视界半径和无量纲耦合常数$\alpha$是有限的，该常数与矢量介子质量与普朗克质量的比值成正比。 在该耦合常数$\hat \alpha$的某个临界值时，视界半径达到最大值。 我们解析地推导出$\hat \alpha$与黑洞解电荷之间的关系，并通过数值计算验证了这一关系。 除了基本的磁电非阿贝尔黑洞外，我们还研究了径向激发的磁电非阿贝尔黑洞和全局规则的引力磁子。 显示英文摘要

摘要： We study static spherically symmetric dyonic black holes in Einstein-Yang-Mills-Higgs theory. As for the magnetic non-abelian black holes, the domain of existence of the dyonic non-abelian black holes is limited with respect to the horizon radius and the dimensionless coupling constant $\alpha$, which is proportional to the ratio of vector meson mass and Planck mass. At a certain critical value of this coupling constant, $\hat \alpha$, the maximal horizon radius is attained. We derive analytically a relation between $\hat \alpha$ and the charge of the black hole solutions and confirm this relation numerically. Besides the fundamental dyonic non-abelian black holes, we study radially excited dyonic non-abelian black holes and globally regular gravitating dyons.
