两个中子之间的Casimir-Polder相互作用及其与四中子态的可能关联
The Casimir-Polder interaction between two neutrons and possible relevance to tetraneutron states
摘要：
我们提出了一个总结，我们最近出版的有关推导的扩展Casimir-Polder色散相互作用的两个中子。动力学极化的中子，最近得到的手征有效理论的目的。在推导CP相互作用时，考虑了与单π介子产生通道的打开和$Δ$共振的激发有关的这些实体的高频/高能行为。详细讨论了自由空间中的中子-中子系统，以及中子-壁和壁-中子-壁系统。然后简要地考虑了共振态四中子系统的情况。的4 n CP相互作用进行评估，以评估其潜在的相关性正在进行的辩论有关的四中子的性质。
英文摘要：
We present a summary of our recent publication concerning the derivation of the extended Casimir-Polder dispersive interaction between two neutrons. Dynamical polarizations of the neutrons, recently derived within Chiral Effective Theory are used for the purpose. An account of the higher frequency/energy behavior of these entities related to the opening of one-pion production channel and the excitation of the $Δ$ resonance are taken into consideration in our derivation of the CP interaction. The neutron-neutron system in free space is treated in details so are the neutron-wall and the wall-neutron-wall systems. The case of tetraneutron (a 4 neutron system) in a resonant state is then briefly considered. The 4n CP interaction is evaluated to assess its potential relevance to the ongoing debate concerning the nature of the tetraneutron.
