磁袋与黑洞

Magnetic Bags and Black Holes

S. Bolognesi

摘要:

我们讨论了引力磁袋,即在引力效应存在下的大量单极子的集群。物理学依赖于无穷远处希格斯场的vev和普朗克质量之间的无量纲比率。我们求解了引力袋方程,研究了从黑洞到黑洞的转变。这种转变的临界耦合是$v_{cr} = \sqrtπ/(4 \sqrt{G})$,它比单个的t Hooft-Polyakov耦合大。我们详细研究了黑洞极限。

英文摘要:

We discuss gravitational magnetic bags, i.e. clusters of large number of monopoles in presence of gravitational effects. Physics depends on the dimensionless ratio between the vev of the Higgs field at infinity and the Planck mass. We solve the equations for the gravitational bags, and study the transition from monopole to black hole. The critical coupling for this transition is $v_{cr} = \sqrtπ/(4 \sqrt{G})$, and it is larger than that of a single 't Hooft-Polyakov monopole. We investigate in detail the black-hole limit.
