论文摘要
如果扩展配置中的能量小于相当数量的自由量子的能量，则携带电荷的标量场通常可以形成非派别孤子（Q-balls）。对于整体Q球，每当潜在的增长速度较慢时，就会存在这种孤子。我们表明，即使没有有吸引力的相互作用，有限温度校正也会产生Q-Ball溶液，因为立方校正的系数通常为负。为了说明这一点，我们考虑使用希格斯字段构建Q球的可能性。我们首先表明，如果标准模型对称性未加盖，则有限温度校正将使Higgs球的存在。然后，我们表明，由标准模型量规玻色子介导的HIGGS自我互动足以防止这些状态在实际标准模型中存在，但是它们可以在各种扩展中存在。
Scalar fields which carry charge can generally form non-topoligical solitons (Q-balls), if the energy in the extended configuration is less than the energy of an equivalent number of free quanta. For global Q-balls, such solitons exist whenever the potential grows slower than quadratically. We show that even in the absence of attractive interactions, finite temperature corrections can generate Q-ball solutions, as the coefficient of cubic corrections is generally negative. As an illustration of this, we consider the possibility of constructing Q-balls using the Higgs field. We first show that the finite temperature corrections would enable the existence of Higgs balls if the Standard Model symmetry was ungauged. We then show that Higgs self-interactions mediated by the Standard Model gauge bosons are sufficient to prevent the existence of these states in the actual Standard Model, but they can be present in a variety of extensions.
