具有负能态的协变Hamilton动力学
Covariant Hamiltonian Dynamics with Negative Energy States
摘要：
在点形式相对论哈密顿动力学框架下研究束缚强子系统的相对论量子力学。考虑到庞加莱群生成元的正确定义所施加的限制，引入了负能态。我们得到的非病态，显然是协变的波动方程，动态包含负能态的贡献。还引入了辅助负能态，专门用于研究强子系统与外部探针的相互作用。
英文摘要：
A relativistic quantum mechanics is studied for bound hadronic systems in the framework of the Point Form Relativistic Hamiltonian Dynamics. Negative energy states are introduced taking into account the restrictions imposed by a correct definition of the Poincaré group generators. We obtain nonpathological, manifestly covariant wave equations that dynamically contain the contributions of the negative energy states. Auxiliary negative energy states are also introduced, specially for studying the interactions of the hadronic systems with external probes.
