T Hooft-Polyakov介子的共振态和束缚态

On resonances and bound states of the 't Hooft-Polyakov monopole

Katie M Russell, Bernd J Schroers

摘要:

我们提出了一个系统的方法,线性化的杨米尔斯希格斯方程的背景下的一个't Hooft-Polyakov的研究,并使用它来统一和扩展以前的研究,其光谱特性。我们表明,四元数配方允许一个紧凑和有效的治疗的线性化方程的BPS限制消失希格斯自耦合,并使用它来研究散射和束缚态。我们专注于部门的广义角动量消失,并分析它的数值,把零能量束缚态,库仑束缚态和无限多的费什巴赫共振到一个连贯的图片。我们还考虑了非零Higgs自耦合的线性化Yang-Mills-Higgs方程,并证实了在这种情况下费什巴赫共振的发生。

英文摘要:

We present a systematic approach to the linearised Yang-Mills-Higgs equations in the background of a 't Hooft-Polyakov monopole and use it to unify and extend previous studies of their spectral properties. We show that a quaternionic formulation allows for a compact and efficient treatment of the linearised equations in the BPS limit of vanishing Higgs self-coupling, and use it to study both scattering and bound states. We focus on the sector of vanishing generalised angular momentum and analyse it numerically, putting zero-energy bound states, Coulomb bound states and infinitely many Feshbach resonances into a coherent picture. We also consider the linearised Yang-Mills-Higgs equations with non-vanishing Higgs self-coupling and confirm the occurrence of Feshbach resonances in this situation.
