关于Electroweak-Skyrmion
More on Electroweak-Skyrmion
摘要：
本文讨论了在标准模型Higgs Lagrangian中加入一般O（p^4）项的拓扑孤子或电弱Skyrmion的性质。我们证明了电弱Skyrmion的质量上限约为10 TeV，这是由现有的实验对O（p^4）项系数的约束得到的。本文还讨论了进一步修改拉格朗日量对电弱-Skyrmion性质的影响，并对早期宇宙中作为暗物质的电弱-Skyrmion的可能产生机制作了评述。
英文摘要：
We discuss the properties of the topological soliton, or the Electroweak-Skyrmion, in the system of the Standard Model Higgs Lagrangian with addition of general O(p^4) terms. We show that the upper bound on the mass of the Electroweak-Skyrmion is about 10 TeV, which is obtained from currently available experimental constraints on coefficients of O(p^4) terms. The impact on the properties of the Electroweak-Skyrmion due to further modification of the Lagrangian is also discussed, and comments on possible mechanisms for the generation of the Electroweak-Skyrmion in the early Universe as a dark matter are given.
