论文摘要

与重力一起进行自我相互作用的骨田理论,通常允许被称为孤子的结合状态。根据场的自旋特性,它们甚至可以携带宏观的内在自旋极化。我们专注于SU($ 2 $)的案例,我们用沉重的希格斯(Higgs)描述了非亚伯理论的两极分化孤子,我们称为“ Yang-Mills Stars”。由于两种自我互动;令人反感的是由于阳米尔斯的结构而引起的,同时是由于希格斯交换而引起的。我们可以拥有多样化的孤子动物园。根据该理论的各种参数,例如Yang-Mills Vector Fields $ M $,Dark Higgs Field $M_φ$的质量以及量规耦合常数$ G $,这些对象在天体物理上可能很大,并且大小和质量变化,并带有大量的固有的旋转和/或Iso-spin和/或Iso或Iso或Iso或Iso或Iso或Iso或Iso或Iso或Iso spin的意义。即使对于向量质量为$ M \ simeq 10 $ eV,我们也可以容纳量规耦合$ g \ lyssim 10^{ - 4} -10^{ - 5} $,仍然逃避子弹群群限制。对于这些参数,可能存在宇宙学上长期存在的孤子,其半径为$ r_ {s} \ sim 10^{5} \,r _ {\ odot} $,并且smases $ m_ {s}} \ sim 10 m _ _ {\ odot} $的内在$ _ {和ISO-Spin极化。作为SU($ 2 $)Higgs模型中Soliton解决方案空间的子集,最后我们还明确讨论了Abelian Higgs模型中的孤子。

Bosonic field theories with self interactions alongside gravity, generally admit bound states known as solitons. Depending upon the spin nature of the field, they can even carry macroscopic intrinsic spin polarization. Focusing on the SU($2$) case, we describe polarized solitons in non-Abelian theories with a heavy Higgs, which we refer to as `Yang-Mills stars'. Owing to both kinds of self-interactions; repulsive ones arising due to the Yang-Mills structure, while attractive ones arising due to the Higgs exchange; we can have a diverse zoo of solitons. Depending upon various parameters of the theory such as the mass of the Yang-Mills vector fields $m$, mass of the dark Higgs field $M_φ$, and the gauge coupling constant $g$, these objects can be astrophysically large with varying size and mass, and carry large intrinsic spin and/or iso-spin giving rise to interesting phenomenological implications. Even for vector mass as large as $m \simeq 10$ eV, we can accommodate gauge couplings $g \lesssim 10^{-4}-10^{-5}$, still evading Bullet cluster constraints. For these parameters, there may exist cosmologically long lived solitons having radii as large as $r_{s} \sim 10^{5}\,R_{\odot}$ and masses $M_{s} \sim 10 M_{\odot}$, carrying $M_{s}/m \sim 10^{66}$ amounts of intrinsic spin and iso-spin polarization. As a subset of the space of soliton solutions in the SU($2$) Higgs model, in the end we also explicitly discuss solitons in the Abelian Higgs model.
