关于超对称泡沫和频谱交叉的一点注记

A Remark on Supersymmetric Bubbles and Spectrum Crossover

M. Shifman, M. Voloshin

摘要:

利用超对称模型中畴壁张力的精确表达式,我们证明了在从弱耦合到强耦合的过程中会发生谱交叉。在弱耦合制度中,基本激发是最轻的状态,而在强耦合制度中,一种特殊类型的孤立子对象-气泡-承担最轻状态的作用。交叉发生在λ^2/(4π)\sim 0.4处。

英文摘要:

Using an exact expression for the domain wall tension in a supersymmetric model we show that a spectrum crossover takes place in passing from weak to strong coupling. In the weak coupling regime elementary excitations are the lightest states, while in the strong coupling regime solitonic objects of a special type -- bubbles -- assume the role of the lightest states. The crossover occurs at λ^2/(4π) \sim 0.4.
