论文摘要
提出了一个核模型，其中核子通过发射和吸收介子以及明确处理介子来相互作用。该模型中的一个核使自己处于具有不同介体数量的状态的量子叠加中。这些状态之间的过渡将核固定在一起。 模型---在其最简单的化身中---应用于杜特隆，后者成为中子普罗顿状态和中子普罗顿 - 梅森状态的叠加。这些状态之间的耦合会导致核子之间的有效吸引力，并导致具有负能量的结合状态，杜特龙。该模型能够重现deuteron的结合能和电荷半径的可接受值。 该模型应在实践中起作用，比现有的非相关核模型具有多个潜在的优势：模型参数数量减少，自然包含少体力以及自然包含介体物理学。
A nuclear model is proposed where the nucleons interact by emitting and absorbing mesons, and where the mesons are treated explicitly. A nucleus in this model finds itself in a quantum superposition of states with different number of mesons. Transitions between these states hold the nucleus together. The model---in its simplest incarnation---is applied to the deuteron, where the latter becomes a superposition of a neutron-proton state and a neutron-proton-meson state. Coupling between these states leads to an effective attraction between the nucleons and results in a bound state with negative energy, the deuteron. The model is able to reproduce the accepted values for the binding energy and the charge radius of the deuteron. The model, should it work in practice, has several potential advantages over the existing non-relativistic few-body nuclear models: the reduced number of model parameters, natural inclusion of few-body forces, and natural inclusion of mesonic physics.
