Nambu模型规范不变性的出现
Emergence of gauge invariance from Nambu models
摘要:
在一个哈密顿非微扰方法的框架下,我们表明,在要求当前的守恒与高斯约束在一些初始时间在一个nonabelian Nambu模型,我们恢复相应的杨米尔斯理论。这样,南布模型中的自发洛伦兹对称破缺就变得不可观测,而戈德斯通模可以用相应的规范玻色子来识别。
英文摘要:
In the framework of a hamiltonian nonperturbative approach we show that after demanding current conservation together with the Gauss constraints at some initial time in a nonabelian Nambu model, we recover the corresponding Yang-Mills theory. In this way, the spontaneous Lorentz symmetry breaking present in the Nambu model becomes unobservable and the Goldstone modes can be identified with the corresponding gauge bosons.
