赝Nambu-Goldstone玻色子中的Higgs辅助Q球

Higgs Assisted Q-balls from Pseudo-Nambu-Goldstone Bosons

Fady Bishara, George Johnson, Olivier Lennon, John March-Russell

摘要:

最近的TeV规模的强耦合动力学的建设,无论是与希格斯部门本身在伪南武-戈德斯通玻色子(pNGB)希格斯模型或非对称暗物质的理论的动机,我们表明,稳定的孤子Q球可以形成从轻π介子类pNGB字段携带一个保守的全球量子数的希格斯场的存在。我们专注于厚壁Q球的情况下,满足所有约束的解决方案存在于一个范围内的参数值。在我们的近似所能达到的极限下,Q球是弱束缚的,并且是参数大的,轻物理希格斯粒子与Q球的相互作用的形式取决于尺度对称性的破缺。

英文摘要:

Motivated by recent constructions of TeV-scale strongly-coupled dynamics, either associated with the Higgs sector itself as in pseudo-Nambu-Goldstone boson (pNGB) Higgs models or in theories of asymmetric dark matter, we show that stable solitonic Q- balls can be formed from light pion-like pNGB fields carrying a conserved global quantum number in the presence of the Higgs field. We focus on the case of thick-wall Q-balls, where solutions satisfying all constraints are shown to exist over a range of parameter values. In the limit that our approximations hold, the Q-balls are weakly bound and parametrically large, and the form of the interactions of the light physical Higgs with the Q-ball is determined by the breaking of scale symmetry.
