超轻标量暗物质的动力学机制

Dynamical mechanism for ultra-light scalar Dark Matter

Jean Alexandre

摘要:

假设一个自相互作用标量场的双阱裸势,与希格斯真空期望值,它表明,非微扰量子校正自然导致超轻粒子的质量$\simeq10^{-23}$ eV,如果这些非微扰效应发生在一个时间与电弱相变一致。这种机制可能是相关的玻色-爱因斯坦凝聚体研究的背景下描述冷暗物质。考虑到与电弱跃迁的数值一致性,提出了一个Higgs场与暗物质场的相互作用势,其中Higgs场的自发对称性破缺除了通常的Higgs机制外,还导致超轻粒子的产生.这个模型也自然地导致希格斯粒子和暗物质粒子之间极弱的相互作用。

英文摘要:

Assuming a double-well bare potential for a self-interacting scalar field, with the Higgs vacuum expectation value, it is shown that non-perturbative quantum corrections naturally lead to ultra-light particles of mass $\simeq10^{-23}$eV, if these non-perturbative effects occur at a time consistent with the Electroweak phase transition. This mechanism could be relevant in the context of Bose Einstein Condensate studies for the description of cold Dark Matter. Given the numerical consistency with the Electroweak transition, an interaction potential for Higgs and Dark Matter fields is proposed, where spontaneous symmetry breaking for the Higgs field leads to the generation of ultra-light particles, in addition to the usual Higgs mechanism. This model also naturally leads to extremely weak interactions between the Higgs and Dark Matter particles.
