不可积量子场论中的扭结和粒子

Kinks and Particles in Non-integrable Quantum Field Theories

Giuseppe Mussardo

摘要:

在这篇演讲中,我们讨论了在两个具有扭折激发的场论中中性粒子的半经典谱的初等推导。我们还表明,在不可积的情况下,每个真空状态一般不能支持两个以上的稳定粒子,因为所有其他中性激发共振,最终将衰减。

英文摘要:

In this talk we discuss an elementary derivation of the semi-classical spectrum of neutral particles in two field theories with kink excitations. We also show that, in the non-integrable cases, each vacuum state cannot generically support more than two stable particles, since all other neutral exitations are resonances, which will eventually decay.
